What kind of stone is white stone? What kind of stone is white stone?

Most of the common white stones are limestone, and there are also stones such as white marble.

Limestone, simply limestone, is named after calcite.

is the main component of carbonate rocks. Sometimes it contains dolomite, clay minerals and detrital minerals, gray, gray-white, gray-black, yellow, light red, brown-red and other colors, the hardness is generally not large, and there is a violent chemical reaction with dilute hydrochloric acid. It belongs to sedimentary rocks according to its genetic classification.

Mineral particles and crystal structures are rare, and the surface is smooth and small granular. The hardness varies, and some dense limestone can be polished. In modern industry, limestone is used to make cement, lime, calcium carbide.

The main raw material is the indispensable flux limestone in the metallurgical industry, and the high-quality limestone is widely used in the manufacture of papermaking, rubber, paint, coating, medicine, cosmetics, feed, sealing, bonding, polishing and other products after ultra-fine grinding.

The main ingredient of white marble is calcium carbonate.

It is a chemical compound that is mainly composed of calcium carbonate, magnesium carbonate, and silicon dioxide.

composition, also contains a small amount of ferric oxide.

aluminum oxide and other components. The white, fine-grained marble, hard and is a fine building and carving material. Basically, it is not soluble in water.

White marble is hard and white, and China is one of the countries in the world with rich limestone mineral resources. In addition to Shanghai, Hong Kong, Hong Kong, Macao, and Menmen, it is distributed in all provinces, municipalities and autonomous regions.

There are many factors that make a stone white, which is mainly determined by the geological conditions of the stone and the purity of the mineral elements it contains and the associated elements. For example, white marble is a carbonate crystalline aggregate formed by the elements of limestone after metamorphism, as well as dolomite, quartzite, magnesite and so on. The color of the stone is white from the surface, but because of the different elements and genesis contained in it, it constitutes the same color or similar color, but it has its own unique name in geological terms.

The white stone is limestone. Limestone is also known as limestone, and its main component is calcite.

It will also contain some clay minerals, dolomite and detrital minerals. Limestone has gray-white, gray, gray-black, yellow, brown-red, light red and other colors, mainly gray-white. The hardness is not very large, and it will have a violent chemical reaction with dilute hydrochloric acid, which belongs to the sedimentary rock.

The role of limestoneThe main use of limestone is in the production of glass. Limestone is the main raw material for the production of glass, in industrial production, limestone can be used as a filling material for rubber, plastic, paper and many other products after processing high temperature and dissolution, and limestone is also the main raw material for the manufacture of cement.

Most of the use of limestone is used in industrial construction, as well as in the construction of houses, because limestone is a naturally occurring item, distributed in various regions, the annual production is still very high. Limestone can be used not only to make glass, but also to smelt steel and make soda ash.

Make table salt and desiccant.

disinfectants, etc.

It is estimated that it is quartz or calcite, and judging from the picture above, there is no picture and no truth.

Quartz is a mineral that can easily turn into a liquid when exposed to heat or pressure. It is also a fairly common rock-forming mineral, found in all three major types of rocks. Quartz is made up of the simplest silica.

The high purity quartz has a vitreous luster, and the pure quartz is colorless, but it has a different color due to impurities that often contain transition elements. Quartz is very stable and does not easily weathered or change into other minerals. Quartz crystals are the hardest natural ore in nature second only to diamonds, and its surface hardness can be as high as Mohs hardness, and it will not be scratched out by iron.

Calcite is a calcium carbonate mineral, which is the most common of natural calcium carbonates. Therefore, calcite is a widely distributed mineral. The crystal shapes of calcite are varied, and their aggregates can be clusters of crystals, granular, massive, fibrous, stalactite, earthy, and so on.

Tapping calcite can get a lot of square pieces, hence the name calcite. The color of calcite varies according to the impurities it contains, such as light yellow, light red, brownish black, etc. when it contains iron and manganese, but it is generally white or colorless.

Quartz pebbles, the main chemical component is silica, the reason for the formation is the broken rock, after long-distance transportation to make the edges and corners disappear, the formation of garden-shaped or oval stones, produced in various rivers, variety, its appearance is mostly round and shaped, mostly black, yellow, blue-gray, the surface is fine and smooth and smooth, the stone is solid, most of them are irregular blocks, with wax or glass luster, translucent. It can cut the glass and leave scratches, no odor and light odor, and it is not easy to heat when it is quickly rubbed.

The fibrous stone is estimated to be asbestos, so it is recommended that you take a look at the picture above to be sure.

Asbestos is a generic name for natural fibrous siliceous minerals, which is a widely used building materials fireproof board.

The silicate mineral fiber is also the only natural mineral fiber, which has good tensile strength.

It has good thermal insulation and corrosion resistance, and is not easy to burn, so it is widely used. There are many types of asbestos, the three most common are chrysotile (white asbestos), amosite (brown asbestos) and crocidotile (blue asbestos), among which chrysotile is the most abundant and widely used.

Asbestos itself is not toxic, its biggest harm comes from its fibers, which is a very small, almost invisible fiber, when these small fibers are released, they can float in the air for a long time and be inhaled into the human body, and the inhaled asbestos fibers can accumulate in the human body for many years, attach and deposit in the lungs, causing lung diseases.

Quartz crystals are white and transparent, many stones are rich in quartz crystals, there is nothing peculiar, as for whether your stone is an ordinary stone, you can only judge after seeing it.

Quartzite is a metamorphic rock mainly composed of quartz (quartz content is greater than 85%), which is formed by metamorphism of quartz sandstone and siliceous rock. It is generally formed by the recrystallization of quartz sandstone or other siliceous rocks through regional metamorphism. It is also possible that quartzite is formed by thermal contact metamorphism of siliceous rocks near magma.

White stones are pebbles or beach stones. It is relatively small in size, but it has a very large effect, such as it can be spread in the courtyard or in the bathroom, the decorative effect is very good, and it can play a non-slip role, especially suitable for toilet use.

Stone: Stone, generally refers to the small rock mass that falls off by the external force of the large rock mass, mostly attached to the surface of the large rock mass, generally into a block or oval, the appearance of some rough, some smooth, solid texture, brittle hard. It can be used to make stone tools and collect stone mines.

Thousands of years ago, our ancestors used stones to make fires. Stones are generally composed of calcium carbonate and silicon dioxide. Li Wenke, director of the Chinese Strange Stone Museum, introduced:

Stone can be used to make fire, beauty, food, jade beauty, etc., stone has grinding stones, drinking Maifan stone water can regulate human metabolism, increase appetite, promote circulation, help to eliminate harmful substances accumulated in the human body due to environmental pollution, so that cells are purified, long-term drinking can receive the effect of prolonging life, stone can be used to build houses, handicrafts, can be used as building materials.
