Product Description
Our company uses fused quartz blocks as raw material. We then process them through grading, impurity removal, crushing, screening, and magnetic separation to produce fused quartz sand of various specifications, tailored to specific applications.
This product exhibits low thermal conductivity, good thermal stability, and a consistent particle size distribution. It is primarily used as a raw material for crucibles, technical ceramics, refractories, and fine casting.
Main Applications
- Quartz crucible raw material
- Casting material
- Raw material for the refractory, ceramic, and glass industries
