Fused Quartz Blocks
Refined quartz sand is melted at high temperatures, rapidly cooled, then crushed and manually graded to form blocky pieces. Main composition: SiO2 ≥ 99.9-99.98%, Fe2O3 ≤ 0.002%. Top-grade appearance is colorless and transparent, with a small portion having a translucent haze. 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 exporting to countries such as Japan, South Korea, the United States, and Europe.
