High Purity Fused Silica Raw Material

Short Description:

Particle size range: 2-200 mesh (10-0.075mm) can be produced according to user’s demand. Quartz sand is used as a raw material and is converted into amorphous silica (fused silica) by high-temperature melting. Fused silica has a very low coefficient of thermal expansion and thermal conductivity, excellent thermal stability, and stable chemical properties. Widely used in photovoltaic, large scale integrated circuits, epoxy resin casting, advanced refractory ceramics, precision casting a...

Particle size range: 2-200 mesh (10-0.075mm) can be produced according to user’s demand.

Quartz sand is used as a raw material and is converted into amorphous silica (fused silica) by high-temperature melting. Fused silica has a very low coefficient of thermal expansion and thermal conductivity, excellent thermal stability, and stable chemical properties.
Widely used in photovoltaic, large scale integrated circuits, epoxy resin casting, advanced refractory ceramics, precision casting and other industries.

SiO2 > 99.9% TiO2 < 50ppm
Fe2O3 < 0.01% MgO < 50ppm
Al2O3 < 200ppm CaO < 50ppm
Na2O < 50ppm K2O < 50ppm
EC 0.9μs/cm
