What is quartz?

Overview of Quartz silica powder

Quartz powder is a continuous tetrahedral mineral composed of silicon and oxygen atoms. Each oxygen atom is shared by two tetrahedrons. Quartz is the second most abundant mineral in the earth's crust after feldspar. There are many kinds of quartz, such as amethyst, rose quartz, smoke crystal and so on.

Quartz is also known as silica powder. Quartz sand is a hard, wear-resistant and chemically stable silicate mineral. Its main mineral composition is SiO2. The color of quartz sand is milky white or colorless and translucent. Hardness 7, bulk density (1.5 for 20-200 mesh), density 2.65, oily luster. Insoluble in acid, slightly soluble in KOH solution. Its chemical, thermal and mechanical properties have obvious anisotropy, and its melting point is 1650 ℃. After the processing of quartzite, the product with fineness below 120 mesh (less than 120 mesh) is called quartz sand, and the product with fineness above 120 mesh is called quartz powder.

Application of Quartz silica powder

1. In the field of coatings and fillers: quartz powder has good scattering and extinction effects, relatively low density and bright color. Its brightness can reach 92-95. It will replace the traditional reflective glass beads for industrial applications and in paints with greatly improved skid resistance.

2. In the industrial production of nylon castings and resin castings, ultra-fine quartz powder is often used to reduce the cooling shrinkage of castings; Adding superfine silica powder to nylon and all resin systems can reduce the shrinkage of the resin during cooling.

3. In the manufacturing of glass and metallurgy industry, optical glass instruments, conductive glass and various packaging cans can be manufactured by using the scattering of ultra-fine quartz powder and good extinction ability.

4. In the foundry industry, quartz powder is used as additive and flux to reduce the shrinkage of castings during cooling, while the high silicon content of quartz powder is used to produce silicon alloy in metal smelting.

Superfine powder mill plays an important role in fine powder processing. It provides high-efficiency, high-capacity and energy-saving equipment for superfine powder. At the same time, it produces quartz powder with different fineness for customers, so as to further expand the application field of superfine quartz powder.

Recently, materials researchers at the Paul Scherrer Institute psi in Switzerland have developed a method that can make a breakthrough in lithium sulfur batteries. In theory, lithium sulfur batteries can provide more energy than today's traditional lithium-ion batteries, but the current prototype shows significant capacity loss after several charges. Therefore, they are not suitable for wide use, such as in electric vehicles. Through their new approach, researchers can gain key insights into how capacity losses occur quickly. They found that adding quartz powder to the liquid composition of the battery could slow the loss.
