Quartz is one of the most common minerals in the Earth’s crust. As a mineral name, quartz refers to a specific chemical compound (silicon dioxide, or silica, SiO2), having a specific crystalline form (hexagonal). It is found is all forms of rock: igneous, metamorphic and sedimentary. Quartz is physically and chemically resistant to weathering. When quartz-bearing rocks become weathered and eroded, the grains of resistant quartz are concentrated in the soil, in rivers, and on beaches. The white sands typically found in river beds and on beaches are usually composed mainly of quartz, with some white or pink feldspar as well. Quartz has great economic importance. Large amounts of quartz sand (also known as silica sand) are used in the manufacture of glass and ceramics and for foundry moulds in metal casting. Crushed quartz is used as an abrasive in sandpaper, silica sand is employed in sandblasting, and sandstone is still used whole to make whetstones, millstones, and grindstones. Silica glass (also called fused quartz) is used in optics to transmit ultraviolet light. Tubing and various vessels of fused quartz have important laboratory applications, and quartz fibres are employed in extremely sensitive weighing devices. Quartz crystal is one of several minerals which are piezoelectric, meaning that when pressure is applied to quartz, a positive electrical charge is created at one end of the crystal and a negative electrical charge is created at the other. These properties make quartz valuable in electronics applications. Electronics-grade manufactured quartz is used in a large number of circuits for consumer electronics products such as computers, cell phones, televisions, radios, electronic games, etc. It is also used to make frequency control devices and electronic filters that remove defined electromagnetic frequencies.
Wedge Silica Refractories
80 - 120 Per Kilogram
1000 Kilogram (MOQ)
silica bricks are made of quartz stone material, the content of sio2 is more than 96%. The nature and craft process of silica bricks are closely related to the crystal transformation of sio2. The density is an important quality indicator of silica bricks. The density of silica bricks should be below 2.38 g/cm 3. The quality of silica brick should be below 2.35 g/cm3. silica bricks have the excellent ability to resist acid slag and acid solution erosion. besides, silica bricks have good high temperature strength, high refractoriness under load about 1640-1680°c, high softening point with temperature. What’s more, silica bricks are also featured with good heat conduction and the refractoriness is 1690~1730°c

Talc Powder
7 - 22 Per Kg
The use of talc in various industries has many benefits. For example, in the cosmetics industry, talc is used as a filler in makeup products and as an absorbent to help control shine and oil. In the pharmaceutical industry, it is used in the manufacturing of tablets and capsules as a lubricant and to improve flow properties. In the plastics industry, it is used as a reinforcing agent and to improve the properties of the final product. Anipolychem’s distribution of talc powder and talc lumps plays a critical role in serving a vast number of industries. Their expertise in talc distribution and their ability to export to other countries have helped them become a leading player in the talc industry.
