Silica Sand & Lump
High-purity silica sand and lump, SiO2 98%+, for glass, foundry, and filtration.
Applications
Silica is the primary raw material for flat glass, container glass, fiberglass, and optical glass, and serves as foundry sand for metal casting owing to its thermal strength and dimensional stability. High-purity grades are supplied for potable and wastewater filtration, ceramics, and refractories, as well as for sandblasting media. Micronized powder is further used in silicones, coatings, paints, and industrial fillers.
