Sources of raw materials

 Colored quartz sand, the raw material comes mainly from refined quartz sand and high purity quartz sand, their chemical properties
significantly affect the quality of colored sand, and its physical and chemical standards are:
         Fine quartz sand
       SiO2≥99—99.5％ Fe2O3≤0.02—0.015％,   selected high-quality ore complex processing. Size range 5 to 480, users can request the production, white appearance or crystalline. Main use: Advanced glass, glass products, refractory materials, melting rock, precision casting, grinding wheel material and so on.
         High purity quartz sand:
       SiO2 ≥ 99.5-99.9% Fe2O2 ≤ 0.005%, is the use of 1-3 high quality natural stone and natural crystal stone, carefully selected, fine processing. Size range 1-0.5mm, 0.5-0.1mm, 0.1-0.01mm, 0.01-0.005mm, according to user requirements.
