Fused Quartz Blocks

Refined quartz sand is melted at high temperatures, quenched rapidly, then crushed and artificially graded to form blocky material. Main composition: SiO2 ≥ 99.9-99.98%, Fe2O3 ≤ 0.002%. First-grade products are colorless and transparent, with a small portion having a translucent foggy appearance. It can be processed into various specifications of sand and powder according to customer requirements.

Main Applications: Used in high-grade refractory materials and electrical & electronic industries. Currently exported to countries such as Japan, South Korea, the United States, and Europe.
