Silica Sand mainly used in:Precision Ceramics----High temperature resistance, heat resistance, friction resistance, acid and alkali corrosion resistance, chemical stability, enhancement of the increase Insulation, etc.
Architecture-----Concrete, cementitious materials, road construction materials, artificial marble, cement physical property test materials (i.e. cement standard sand), etc.
Chemical----Raw material of silica compounds and water glass, etc., filler of sulfuric acid tower, amorphous dioxide Micro-powder.
Mechanical----The main raw material of casting sand, abrasive materials (sandblasting, hard abrasive paper, sandpaper, sand). etc.)
Electronics----High purity silicon metal, optical fiber for communication, etc.
Plastics----Filler (can improve abrasion resistance)
Coatings-----Fillers (to improve weathering resistance of paints)
Metallurgy----Raw materials or additives, solvents for silicon metals, ferrosilicon alloys and aluminum silicon alloys, etc.
Aviation, aerospace-----Its internal molecular chain structure, crystal shape and lattice pattern of change, so that it has the resistance to temperature,small coefficient of thermal expansion, highly insulating, corrosion resistance, piezoelectric effect, resonance effect
