Silica sand is an important industrial and mineral raw material and
it is widely used in glass?casting?ceramics and
refractories?metallurgy, construction, chemical, plastic, rubber
and abrasive, etc. 1. Glass: The principal raw material of flat
glass?float glass?glass products(glass cups?glass bottles?glass
tubes,etc.)?optical glass?glass fiber?glassware?conductive
glass?glass-fibre fabric?the ray preventing special glass, etc. 2.
Ceramics and refractories: The raw material of the embryo and the
glaze of porcelain?high silica silica brick, and silicon carbide
used for kiln. 3. Metallurgy: The raw material?additive or rholite
of silicon metal?ferro-silicon alloy?silicon-aluminium alloy, etc.
4. Construction: The test material of physical properties (Cement
standerd sand) of concrete?cementitious materials?road
materials?artificial marble, etc. 5. Chemical: The raw material of
silicon compound?sodium silicate and the filler of Sulfuric acid
absorption tower?Amorphous silica powder. 6. Machinery: The
principal raw material of foundry sand and abrasive substance(sand
blasting?hard abrasive paper?emery paper?abrasive band, etc.). 7.
Electron: High purity silicon metal?fiber-optic for communication,
etc. 8. Rubber?plastic?Filler (to improve wear resistance) 9.
Coating material: Filler (to improve the acid resistance of coating
material). *0. Aviation?spaceflight: It�s molecular chain
structure?crystal shape and the change rule of crystal lattice make
it have the characteristics of thermostability?Low coefficient of
thermal expansion?high insulation?corrosion resisting?piezoelectric
effect?resonance effect and it's unique optical properties.
