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.

Volcanic rock commonly known as pumice or porous basalt, also known as pumice rock, it is a dense porosity of molten magma condensed by volcanic eruption glassy lava, the porosity volume accounted for more than 50% of the volume of the rock.

Perlite is a commonly used building insulation material in the construction industry and is often used in external wall insulation. Perlite has strong water absorption and is easy to seep water and gain weight, and the outer layer needs to be a waterproof coating when it is usually used for external wall insulation.

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.

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.

Volcanic stone (volcanic rock or pumice) is a kind of glassy lava with dense pores formed by the rapid expansion of internal gas due to the sharp reduction of pressure after the sudden cooling of magma during the volcanic eruption. The pore volume accounts for more than 50% of the rock volume. It is called pumice because of its many pores, light weight and ability to float on the surface of the water. It is characterized by high strength, heat preservation, heat insulation, sound absorption, fire protection, acid and alkali resistance, corrosion resistance, and no pollution, no radioactivity.

Quartz sand is quartz particles formed by crushing and processing of 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.

The density characteristics of volcanic rocks depend on their composition and formation process.

Fused quartz is the amorphous (glassy) state of silicon oxide (quartz, silica), which is a typical glass with a long-range disordered atomic structure. It provides its high service temperature and low coefficient of thermal expansion through a three-dimensional structure cross-linking.
