Fused silica is a material for making ceramic mold shells in investment casting manufacturing process.

This material has high chemical resistance, low thermal expansion and good thermal shock resistance. 

Main applications for this molding compound include  precision castings & refractory.

Chemical Content: SiO2 (99.92 - 99.50%) ; Fe2O3 (0.001 - 0.045%) ; Al2O (30.020 - 0.050%) 

Content depends on material grade.

Fused silica particle size is available upon request and can be requested as sand or as a powder.
