Crucible generalization

There are many models and specifications of the crucible, which are not limited by the production scale, batch size and variety of smelted substances in the application, and can be selected arbitrarily, with strong applicability, and can ensure the purity of the smelted substance. After use, place it in a dry place to avoid rainwater intrusion; Bake slowly to 500 degrees Celsius before use.

before use. The crucible should be fed according to the capacity of the crucible, and it should not be squeezed too tightly, so as to avoid the thermal expansion and cracking of the crucible. When taking out the molten metal, it is best to scoop it out with a spoon, and use the caliper as little as possible, if the caliper and other tools should be consistent with the shape of the crucible, so as to avoid excessive local force and shorten the service life.

The service life of the crucible is related to the usage, and the strong oxidizing flame should be avoided from being sprayed directly on the crucible, which will make the oxidation of the crucible raw material short-lived.

The raw materials for the production of ceramic crucibles can be summarized into three types. One is crystalline natural graphite, the second is plastic refractory clay, and the third is calcined hard kaolin.

Skeleton-like clinker. Since 2008, high-temperature resistant synthetic materials such as silicon carbide have been used.

Alumina corundum.

and ferrosilicon as skeleton clinker for crucibles. This clinker has a significant effect on improving the quality of crucible products, enhancing crucible density and mechanical strength.

A crucible is a container used to heat and melt a substance, and the main uses include:

1.Smelting and casting metals: Crucibles are widely used in metal processes to heat metals to their melting point and undergo processes such as melting, casting, molding, etc.

Metal crucibles can hold molten metal, keep it within the right temperature range, and be able to accommodate changes in the volume of molten metal.

2.Melting glass: Crucibles are also used in the glass manufacturing process to melt glass raw materials. Molten glass can be cast into different shapes of containers, utensils, glassware, etc.

3.Chemical experiments: In chemical laboratories, crucibles are often used for heating, drying, and burning of substances. It can withstand high temperatures and has good corrosion resistance to many chemicals, so it is suitable for various chemical reactions and experimental operations.

4.Fired ceramics and glazes: Crucibles are used in ceramic manufacturing to fire ceramics and glazes. It can hold ceramic blanks and glazes, and complete the sintering and glazing process at high temperatures.

It is made of refractory materials such as magnesium oxide, clay, graphite, should, corundum, and ceramic. It is a cup-shaped vessel that is used in laboratories to heat liquids or solids at high temperatures. The application is not limited by the production scale, batch size and type of molten material, and can be selected arbitrarily, with strong applicability, which ensures the purity of the molten material.

2. Feed according to the capacity of the crucible, avoid too tight, so as to avoid thermal expansion and cracking of the crucible.

3.When removing molten metal, it is best to scoop it out with a spoon and use as few calipers as possible. If tools such as calipers are used, they should conform to the shape of the crucible to avoid excessive local stress and shorten the service life.

4.The service life of the crucible is related to the use, and the strong oxidizing flame should be avoided to spray directly on the crucible, and the raw material of the crucible is oxidized for a short life.

The material of the crucible is not a single fixed, the materials for making the crucible are varied, used in different environments and conditions, the materials are different, the common ones are stainless steel, magnesia, clay, graphite, quartz, corundum, ceramics, silicon carbide, nickel, iron, gold, silver and other materials.

The crucible is a kind of cup-shaped vessel often used in the laboratory, which can be used to heat liquids, solids and other substances at high temperatures, so the materials made need to have good high temperature resistance.

There are many models, specifications and styles of crucibles, which can be selected arbitrarily without being limited by factors such as production scale, batch size, and material variety in application, and can ensure the purity of the substance.

After using the crucible, it needs to be placed in a dry place to avoid being soaked in water, and it needs to be baked to 500 degrees before use.

The main ingredient of the crucible is alumina (Al2O3), which is resistant to acids and alkalis at high temperatures.

Crucibles are made of extremely refractory materials such as clay, graphite, china clay or metal compounds that are difficult to melt

<>1. The main components of porcelain crucible are alumina and silicon dioxide. It can withstand high temperatures of about 1200 degrees Celsius.

2. The main raw material of graphite crucible is crystalline natural graphite. Therefore, it maintains the original physical and chemical properties of natural graphite.

3. The corundum crucible is composed of porous molten alumina, which is hard and melt-resistant.

4. The main raw material of quartz crucible is high-purity quartz sand.

It is made of refractory materials, commonly used are magnesia, clay, graphite, quartz, corundum, ceramics, etc. It is a cup-shaped vessel used in laboratories to heat liquids or solids at high temperatures. In the application, it is not limited by the production scale, batch size and the variety of smelted substances, and can be arbitrarily selected, with strong applicability, and can ensure the purity of the smelted substances.

The appearance of a crucible can vary depending on the use and material, but it usually has the following characteristics:

1.Shape: Crucibles are usually round or conical in shape, with a wider base and a narrower upper part. This shape helps the crucible to transfer heat evenly during heating and facilitates the pouring of the substance.

2.Material: Crucibles are usually made of high-temperature resistant materials such as quartz, smelted porcelain, graphite or ceramic. Crucibles made of different materials may have slightly different looks and textures.

3.Opening: The crucible has an opening that is used to put the substance in or pour it out. The opening is usually located at the top of the crucible and can be round rock sock-shaped or slightly tapered.

4.Size: The size of the crucible can vary according to specific needs. They can be small laboratory crucibles or large industrial crucibles.

Metal crucibles, ceramic crucibles, graphite crucibles.

Evaporation dish. <>

This is the evaporation dish. The evaporation dish is a vessel used for evaporation, concentration of solutions or burning of solids. The evaporation dish has good stability to acid and alkali, and can withstand high temperatures, but it should not be cooled; Different materials and different corrosion resistance should be appropriately selected according to the properties of solutions and solids; Commonly used is porcelain evaporation dishes, but also made of glass, quartz, platinum, etc.

This is the crucible. A crucible is a chemical instrument.

It is an important component of melting and refining metal liquids as well as solid-liquid heating and reaction vessels, and is a vessel to ensure chemical reactions.

The foundation for smooth progress.

A crucible is a container that is mainly used in the process of melting and heating. It is usually made of graphite, porcelain, ceramic, or metal and comes in different shapes and sizes to accommodate different types and scales of heating or smelting processes.

In chemical experiments, crucibles are often used to heat solid reagents, such as dried compounds or precipitates, in order to bring them into a liquid state for subsequent experiments. In the smelting of metals and alloys, crucibles are often used to melt metals and alloys, which are then able to pour the molten metal or alloy into other containers.

In addition to chemical experiments and metal smelting processes, crucibles can also be used in industries such as high-temperature sintering, steelmaking, and glass manufacturing. In addition, in the industrial sector, crucibles can also be used to hold and store materials at high temperatures.

In general, the Crucible is a very commonly used tool, and it has a wide range of applications in the fields of chemistry, metallurgy, and materials science. Due to the different materials and shapes, the use of crucibles is also very flexible, and can adapt to different forms of heating and melting, so it has a wide range of uses and significance. <>
