Natural zeolite is an emerging material that is widely used in industry, agriculture, defense and other sectors, and its use is constantly expanding. Zeolite is used as an ion exchanger, adsorption separating agent, desiccant, catalyst, cement mixture.

Quartz sand is quartz particles formed by crushing and processing quartz stone. Quartz stone is a non-metallic mineral, which is a hard, wear-resistant and chemically stable silicate mineral. The color of quartz sand is milky white, or colorless translucent, Mohs hardness 7.Common specifications are: 0.5-1mm, 1-2mm, 2-4mm, 4-8mm, 8-16mm, 16-32mm, 10-20 mesh, 20-40 mesh, 40-80 mesh, 100-120 mesh.

Vermiculite is a natural, inorganic, non-toxic mineral that expands under high temperature. It is a relatively rare mineral, belonging to the silicate group. Its crystal structure is monoclinic crystal system, and its appearance is similar to mica.

Non-toxic. Medical stone is a compound mineral or medicinal rock that is non-toxic and harmless to organisms and has certain biological activity. The main chemical composition of medical stone is inorganic silicaluminate. Including SiO2, Al2O3, Fe2O3, FeO, MgO, CaO, K2O, Na2O, TiO2, P2O5, MnO, etc., also contains some of the major elements required by animals, such as: K, Na, Ca, Mg, Cu, Mo and other trace elements and rare earth elements, about 58 kinds of.

Coated sand is mainly made of high-quality natural quartz sand as raw sand, thermoplastic phenolic resin, ulotropine and reinforcing agent as raw materials. According to the different technical requirements of users, the ratio is appropriately adjusted in terms of curing speed, film removal, fluidity, collapsibility, casting surface finish, storage and so on. It is one of the best modeling materials for cars, tractors and hydraulic parts.

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.

Zeolite is mainly volcanic sedimentary rock, because the organic matter in the sedimentary rock is liquefied or vaporized, and the formation of fine holes, and these holes are just the living places of nitrifying bacteria. Zeolite is composed of aluminosilicate and other minerals, and has cation adsorbability.

Emery, SiC, also known as silicon carbide. Pure is a colorless crystal. Density 3.06~3.20. It's very hard, about 9.5 degrees Morse. Generally, it is a colorless powdery particle. After grinding, it can be used as grinding powder, polishing paper, and friction surfaces for grinding wheels and whetstones. It is made by heating sand and carbon in an electric furnace.

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.

Glass sand is divided into colored glass sand and transparent glass sand, transparent glass sand looks like white sugar, glass sand is used for glass surface decoration, such as glasses, vases, lampshades and so on. Glass sand is fused together with glass workpieces to form a concave and convex three-dimensional surface,

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.

Shell sand is a common building material, which is made of crushed shells and has a certain hardness and durability. Shell sand has a wide range of uses and can be used in many aspects such as interior walls, exterior walls, floors and ceilings.

Quartz stone is a non-metallic mineral, which is a hard, wear-resistant and chemically stable silicate mineral. The color of quartz sand is milky white, or colorless translucent, Mohs hardness 7.Quartz sand is an important industrial mineral raw material, non-chemical dangerous goods, widely used in glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter media and other industries.

The use of emery is very wide, for example, the glass industry, used to grind glass rough edges, the stone industry is used to grind marble, the metal industry is used for sandblasting, rust removal, grinding, etc., and we use emery made of wear-resistant floor, used in the field of industrial floor.

Pine bark can adjust the acidity and alkalinity of the soil, provide nutrients for the growth of plants, and pine bark planting can maintain good water permeability and air permeability of the soil.

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.

Sand casting is an economical way to produce parts in a variety of metals. Shell mold casting can be an alternative process to consider given specific part design needs. This blog post introduces the shell mold casting process and compares it with sand casting so readers may understand their respective strengths and limitations.

Gulf State Park holds some of the most endangered archaeological deposits in the State of Alabama. Even though these sites are located within the protected area of the park, rising sea levels and damage caused by severe coastal storms will one day likely erase what remains of these fragile reminders of the people who were here before us. Even today, understanding the complex system of interconnected waterways, residential sites, and mounds is made that much more difficult by the centuries of storms and historic changes to the landscape.

Ceramsite is made of clay, slate, shale, coal gangue, and industrial solid waste and other raw materials, and is sintered by ceramics.
