fused silica grain：The use of refined products high temperature melting quartz sand, with its molecular orderly disorder to order, so that they can become high purity transparent amorphous-frit, Its main divided into SiO₂:99.8-99.99%,Fe₂O₃≤0.002%,5,000 tons annually, mainly for senior refractories and the electrical and electronics industries.
　　Now using advanced processing technology and processing equipment, materials right after the collision crusher, Separator, plastic machine, screening machine, jet mill, vibrating mill, grading machine and processing technology into a variety of size of fused quartz powder. The products in the course of processing is no intermediate mixed with impurities, basically guarantees that the original content remains unchanged. Users can size requirements.

The use of refined products high temperature melting quartz sand, with its molecular orderly disorder to order, so that they can become high purity transparent amorphous-frit, consists of SiO₂:99.8-99.99%,Fe₂O₃≤0.002%,5,000 tons annually, mainly for senior refractories and the electrical and electronics industries.

The product is the quality of fused silica sand, or by jet mill vibration mill grinding, classification processed. Performance on the performance coefficient of expansion of small, low stress and chemical corrosion resistance, and a good radiation, the advantages of low-level radioactive, as a closed IC plastic closures expected, mobility, and spilling less Filled with a large quantity of the outstanding merits. Also be used epoxy castable, potting materials, silicon gel as senior refractories, and metallurgical industries, the annual 2,000 tons.
