New Ceramic Sand Replace Foundry Chromite Sand for Casting

Ceramic foundry sand also known as fused ceramic, quartz sand is a senior alternative.

Ceramic foundry sand is a high heat resistance, low thermal expansion, and spherical artificial casting sand obtained by spray treatment of a high oxidizing raw material in a molten state to recrystallize. Dense structure, grain shape is very spherical, smooth surface and small surface area.
