Hello, I would like to know what is the difference between borosilicate glass and ordinary glass?

1. Raw material composition: high borosilicate glass contains boron trioxide and silica, and the amount of ordinary glass is higher, and the boron content can even reach 14%, and the silicon content can reach 80%. The silicon content of ordinary flat glass is about 70%, and ordinary glass generally does not add boron, but sometimes it is up to 1%.

2. Glass characteristics: Gaopeng glass has low expansion coefficient, high softening point, and good resistance to quenching and heating. Its expansion coefficient is about 32 33*10 (-7), and ordinary glass is about 80-100*10 (-7); It can withstand quenching and heat and cold up to about 200 300 degrees Celsius.

3. Uses: Mainly used for the production of glass instruments, glass pot lids, chemical equipment, etc.

The biggest feature of borosilicate glass is that it has a very low coefficient of thermal expansion, that is, it is not sensitive to temperature, and there is no common thermal expansion and contraction of general objects, so it has high temperature resistance and high thermal stability - resistance to cold and thermal shock. As for the strength, there is nothing special about it, and it is impossible to resist falls.

The difference is to burn with fire, ordinary glass burns a point and quickly breaks, but high borosilicate glass will not.

Actually, that's what I do. Ordinary canned bottles, if they are left outside for a long time in winter, they will explode as soon as hot water is added! And for borosilicate glasses, you just put it at -30 and add 100 hot water!

It doesn't have anything either! This cup is heated to 500+ temperatures when it leaves the factory to ensure that it does not fry!

Hello dear, 1. The difference is that borosilicate glass does not contain alkali metal oxides. 2. High borosilicate glass (also known as hard glass) is made by using the conductive properties of glass at high temperatures, and the glass is melted by heating inside the glass, and processed by advanced production technology. It is a special glass material with low expansion rate, high temperature resistance, high strength, high hardness, high light transmittance and high chemical stability, which is widely used in solar energy, chemical industry, pharmaceutical packaging, electric light source, craft Zheng Sui jewelry and other industries because of its excellent opening performance.

Its good performance has been widely recognized by all walks of life in the world, especially in the field of solar energy, which has been widely promoted in developed countries such as Germany and the United States. 3. Borosilicate glass is a high-boron-low silicaborosilicate glass that does not contain alkali metal oxides. Coronal glass and barium coronal glass belong to alkali-containing borosilicate glass systems.

The crown glass is an alkali-free borosilicate glass system. The gradual increase in the content of B2O5 in borosilicate glass is a phenomenon called boron anomaly.

High borosilicate glass has good fire resistance, high physical strength, and is non-toxic compared with general glass, and its mechanical properties, thermal stability, water resistance, resistance to alkali, acid resistance and other properties are greatly improved. It has excellent acid, alkali and water resistance, superior corrosion resistance, good thermal stability, chemical balance and electrical properties, so it has the characteristics of chemical erosion resistance, thermal shock resistance, good mechanical properties, and high temperature resistance. The tensile strength of borosilicate glass will be higher than that of ordinary glass, so its cracks will also be relatively large, and it will be broken as a unit rather than ordinary glass.

Therefore, the tensile strength of borosilicate glass is also different from that of ordinary glass.

Hope it helps, hope!

1. The composition of raw materials is different: the main components of borosilicate glass are boron oxide and silicon dioxide. The amount of silica is higher than that of ordinary glass, and the boron content can even reach 14%, and the silicon content can reach 80%.

The silicon content of ordinary flat glass is about 70%, usually without boron, but sometimes it is up to 1%.

2. The ability to resist cold and hot impact is different: the boron and silicon materials used in high borosilicate glass actually replace a large number of harmful heavy metal ion components in raw glass, thereby improving the cold and hot impact resistance of glass, so the ability of high borosilicate glass to resist cold and hot impact is different from that of ordinary glass.

3. Different uses: high borosilicate glass is mainly used in household appliances (glass panels inside ovens, microwave oven trays, stove panels, etc.). Ordinary glass is widely used in mosaic building doors, windows, walls, interior decoration, etc.

First, the nature is different.

1. High borosilicate glass is a kind of glass with enhanced fire resistance. The manufacturing process involves the addition of glaze, silicate sand, soda and lime.

2. Glass is an amorphous inorganic non-metallic material, which is generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw material, and a small amount of auxiliary raw materials are added. Its main components are silica and other oxides.

Second, the scope of application is different.

1. High borosilicate glass: widely used in various fields such as chemical industry, aerospace, military, family, hospital, etc., it can be made into lamps, tableware, standard plates, telescopes, washing machine observation holes, microwave ovens, solar water heaters and other products, with good promotion value and social benefits.

2. Glass: widely used in architecture, daily use, art, medical, chemical, electronics, instrumentation, nuclear engineering and other fields.

Summary. The difference between borosilicate glass and borosilicate glass 1, the composition of raw materials is different: the main components of borosilicate glass are boron oxide and silicon dioxide.

The amount of silica is higher than that of ordinary glass, and the boron content can even reach 14%, and the silicon content can reach 80%. The silicon content of ordinary flat glass is about 70%, and boron is generally not added, but sometimes it is up to 1%. 2. The ability to resist cold and hot shock is different

The boron and silicon materials used in borosilicate glass actually replace a large number of harmful heavy metal ions in raw glass, thereby improving the cold and heat impact resistance of glass, so the ability of high borosilicate glass to resist cold and heat shock is different from that of ordinary glass. <>

What is the difference between borosilicate glass and borosilicate glass.

The difference between borosilicate glass and borosilicate glass 1, the composition of raw materials is different: the main components of borosilicate glass are diboron and silica. The amount of silica is higher than that of ordinary glass, and the boron content can even reach 14%, and the silicon content can reach 80%.

The silicon content of ordinary flat glass is about 70%, and boron is generally not added, but sometimes it is up to 1% if you regret it. 2. The ability to resist cold and hot impact is different: the boron and silicon materials used in high borosilicate glass actually replace a large number of harmful heavy metal ion components in raw glass, thereby improving the cold and hot impact resistance of glass, so the ability of high borosilicate glass to resist cold and hot impact is different from that of ordinary glass.

3. Different uses: high borosilicate glass is mainly used in household appliances (glass panels inside ovens, microwave oven trays, stove panels, etc.). Environmental Engineering, Chemical Engineering (Resistant Lining, Chemical Reactors, Safety Mirrors); lighting (cover glass for spotlights and high-power flood lighting fixtures); solar power generation (solar electric width imitation pool substrate); precision instruments (optical filters); semiconductor technology (wafers, display glass); medical technology, bioengineering; Full protection of Anda slag (bulletproof glass). Ordinary glass is widely used in the <> of inlaid buildings, such as smart doors and windows, walls, and interior decoration

What both types of glass have in common is their resistance to thermal shock. The differences are: the former has no strength and is fragile; The latter has good impact strength and can not be broken easily.

1. The coefficient of thermal expansion is different

Borosilicate glass has a very low coefficient of thermal expansion, about one-third that of ordinary glass. This will reduce the effects of temperature gradient stresses and result in greater resistance to fracture.

2. The main ingredients are different

Ordinary glass is soda-lime silicate glass, the main component is silicon dioxide; The main components of borosilicate glass are boron oxide and silicon dioxide, which are made by adding sodium silicate sand, soda and ground lime to the manufacturing process of ordinary silicate glass. The boron content and silicon content of high borosilicate glass can reach 14% and 80% respectively, while boron is generally not added to ordinary glass species.

3. The tensile strength is different

The tensile strength of borosilicate glass is higher than that of ordinary glass, so the cracks are also relatively large, which is the fragmentation of the unit, not the fragmentation of ordinary glass.

4. The ability to resist cold and thermal shock is different

High borosilicate glass uses boron and silicon materials to replace a large number of harmful heavy metal ions in raw glass, which improves the performance of glass resistance to cold and thermal shock, and even if the temperature changes abruptly, the glass will not burst. If you add hot water to an ordinary glass that is placed outdoors in winter, it will expand and explode due to heat. Even if the borosilicate glass is placed in an environment of -30, it will not explode if you add 100 hot water.
