material: standard powders available -325 mesh, -200 mesh, -120 mesh
special features: extremely low coefficient of thermal expansion, consistent chemistry and carefully controlled particle size distribution.
fused silica for investment casting / refractory applications: several grades of coarse fused silica grains (stuccos) and powders (flours) for the investment casting and refractory industries. due to fused silica's low thermal conductivity and excellent thermal shock resistance, it is widely used in both industries.
