Coral sand is a fragment of coral or shell that consistently releases calcium carbonate and comes in a variety of sizes and sizes. The biggest feature of coral sand is that it is rich in micropores, suitable for the survival of a large number of biochemical bacteria, and can be used as a filter material.

Calcium powder can be divided into: heavy calcium powder, light calcium powder, active calcium powder, flue gas desulfurization calcium powder, ultra-fine calcium carbonate and so on.

Dolomite powder is an anhydrous carbonate mineral powder, mainly composed of calcium and magnesium carbonate. It can be used as raw materials for the production of high-grade glassware, medical bottles, and optical glass.

Washed stone is a decorative material made of natural stone, through a special treatment process, so that the fine particles on the surface of the stone are removed, exposing the natural texture and color of the stone. This treatment can highlight the texture and beauty of the stone, while increasing its durability and anti-slip properties.

Microsilica powder is a new kind of material,Microsilica powder is a new material with high surface area, a large number of pores, high and low temperature stability, biological inertness and so on. Its application field is very wide, can be used in petroleum catalyst, environmental protection materials, biomedicine and many other fields.

Alumina powder is made of liquid aluminum hydroxide by extrusion solidification, which contains a variety of elements, and the content is high, the overall density is higher than the general aluminum powder. The surface of alumina powder is closer to the ideal surface than that of other metal powders, so it has good exhaust performance. The particle size of alumina powder is generally 90-100 microns, has good suspension, no load charge, can be oxidized at low temperatures, and has excellent electromagnetic characteristics.

Fluorite (Fluorite) is also called fluorite. A mineral commonly found in nature that is symbiotic with many other minerals and occurs in many parts of the world, [1] with five effective varieties. The main component is calcium fluoride (CaFz). Crystallized into octahedrons and cubes. The crystal is glassy, bright and changeable color, brittle quality, Mohs hardness of 4, melting point of 1360℃, with complete cleavage properties. Some samples can emit light when subjected to friction, heating, ultraviolet irradiation, etc.

Colored sand is divided into natural colored sand, sintered colored sand, temporary dyed color sand, permanent dyed color sand. Its characteristics are: bright color, acid and alkali resistance, ultraviolet resistance, do not fade. Natural color sand: It is crushed by natural ore, which does not fade but has more impurities. Temporary dyeing color sand: bright color, easy to decolorize.

Wheat flour powder is widely used in medical care, food, beverage, water purification, sewage treatment, anti-corrosion, deodorization, preservation, decontamination, porcelain production, planting and aquaculture and other fields.

mineral powder is a general term for stone powder and its substitutes that meet engineering requirements. It is the product of grinding ore processing, is the first step of ore processing and smelting, and is one of the most important steps. The hydrophilic coefficient of mineral powder is the ratio of the volume of expansion per unit of mineral powder in the same water (polar molecules) and the same volume of kerosene (non-polar molecules). Hydrophilic coefficient of mineral Powder in Highway engineering < The mineral powder of 1 is called alkaline mineral powder.

Corn cob is made from high quality corncob crushing processing through strict screening, cream-colored or yellow-brown.organize uniform, suitable hardness, good toughness, strong water absorption, good wear resistance and other advantages in the use of the process is not easy broken.

Iron powder is one of the most important metal powders. Iron powder is the largest in powder metallurgy production, and its consumption accounts for about 85% of the total consumption of metal powder.

Medical stone is a kind of natural ore with porous, light weight and high temperature resistance. It is widely used in the fields of building materials, agriculture, horticulture, fireproof materials and industrial filtration, and plays an important role.

Geophagy has been considered as an adaptive behavior in humans and animals (1) and the clays have been considered the healing materials from ancient times. As geophagia is an occasionally habits of animals and humans (babies and pregnant women), physiologically it is assumed that earth might have some beneficial effects on body function. Bentonite is absorbent aluminium phyllosilicate clay. It is named after Fort Benton, Wyoming where its largest sources are found. Its other name, Montmorillonite clay, stems from the region of France called Montmorillon, where it was first found. It has been used and eaten from ancient time till now as human believes in its therapeutic benefits. When it is mixed with water a paste is formed which has been used both externally and internally. In some places such as Iran, it has been widely used as a hair cleanser from old time. There is enough literature showing its safety after chronic oral consumption (2–6). As this clay is abundant, non-expensive and natural, this article aimed to review the scientific papers reporting the effects of this clay on body.

Silica ash, also known as silica powder, also known as micro-silica powder or silica ultrafine powder, generally referred to as silica ash. Silica fume is a kind of ultrafine silica powder material formed by the rapid oxidation and condensation of SiO2 and Si gas and oxygen in the air during the smelting of ferrosilicon alloy and industrial silicon.

Mica, a mineral that has been used for centuries, is not just a pretty face; it's a versatile material with a rich history. Mica Powder, derived from this natural gem, adds a touch of glamour to various applications, from cosmetics to construction.

Bentonite is a very old clay that has been used as a remedy for many things. The fine powder forms when volcanic ash ages. It’s named after Fort Benton, WY, which has a lot of it. But it’s found all over the world. It’s also known as Montmorillonite clay after a region in France with a large deposit. And you may hear it called calcium bentonite clay.

Calcium fluoride is an inorganic compound that is colorless crystal or white powder. Insoluble in water, slightly soluble in inorganic acid, react with hot concentrated sulfuric acid to produce hydrofluoric acid. In general, calcium fluoride is prepared by the interaction of calcium carbonate with hydrofluoric acid or by repeated treatment of fluorite powder with concentrated hydrochloric acid or hydrofluoric acid.
