Advantages of fused silica sand

    Fused quartz sand (fused quartz) is amorphous silicon dioxide (fused temperature is 1800-2000 ℃) produced by fused method. Then, according to different uses, it is processed by special machinery to remove impurities, screen and produce massive, granular and powdery products. This quartz product has very low thermal conductivity and excellent thermal stability. The following is a brief introduction to the advantages of fused quartz sand.

The main advantages of fused silica sand are as follows:

1. Near zero thermal expansion

2. Excellent thermal stability

3. High purity (high content of SiO2, low content of Fe, K, Na, Ti, etc.)

4. Stable chemical properties

5. Special machinery control production, stable particle size distribution
