1. Product Description of Ceramic Sand
Ceramsite sand is also called as ceramic foundry sand,it selected the high quality bauxite as main material,
then fused in arc furnace,finally made into different size through special technology.
It contains 70% Min Al2O3,its chemical composition is very similar to the one of black fused alumina,while
they are quite different since they are made through different technology after the melting process, then
achieved different shape and applications. Ceramsite sand is mainly used for casting industries,while black
fused alumina is used for abrasives,anti-skip roads etc.

3. Main Features of Ceramic Sand
High refractoriness over 1790℃;
Good sphericity;
High recycle utilization rate;
Good collapsibility;
Low thermal expansion.
4. Main Applications of Ceramic Foundry Sand:
Widely used resin sand: phenolic resin coated sand,hot-core box resin sand,blow hardening cold core resin
sand,self-hardening sand;
Lost Foam casting;
Investment casting;
Sodium silicate sand;
Casting coating;
Drainage sand;
Alloy surface treatment.
5. Why ceramsite is widely used in lost foam casting?
Ceramsite effectively solves casting defects such as sand inclusions and pores,improve the product quality,
reduce the cleaning and grinding costs, also increase the product yield by 7-10%.
Ceramsite has good abrasion resistance, low dust,its annual loss rate does not exceed to be 5%.
So it is widely used for lost foam casting industries,suitable for production of casting iron,casting steel,hadifield
steel etc.
6. How Ceramic sand affects the quality of casting quality?
The alumina content of ceramic sand will affect its crushing rate &durability,so casting made by different materials has
different alumina requirement for ceramic sand.High alumina ceramic sand is required when needing multiple strong
regeneration;
The mud content of ceramic sand also affects the casting quality;
The average fitness and particle size distribution also affects the casting quality.
