Ceramic sand is characterized by high fire resistance (＞1800 ℃), small angle shape coefficient (＜1.06, nearly spherical), low acid consumption (neutral material), small amount of binder added (reduce the amount of binder added by 30% – 50%), high strength, no crushing, no dust, non-toxic, etc. It meets various casting demands with excellent chemical compositions. Casting quality,

Raw Material-Bauxite Raw aluminum cores contain lots of free water, crystal water, and low melting point components. Using natural aluminum cores to produce consumes a large amount of electric energy. It is challenging to eliminate low melting point components, causing the product’s instability and affecting product quality. It is essential to calcine the raw aluminum

Ceramic Foundry sand ,also called as Fused Ceramic Sand is made from high quality bauxite, by re-fused and blown to ball type. With advantage of fine surface smooth finish and air permeability, it is a new type casting material for precision casting, coated sand and self hardening sand etc.At the present, Ceramsite is acknowledged in the

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

Ceramsite sand is high grade green casting material, made of high Alumina Calcined Bauxite, processed through fusing, spraying, sieving, get rid of impurity and special procedures. With ideal spherical shape, excellent fluidity and filling property, Ceramsite sand is widely used in various sizes of steel/iron/alloy casting parts. It is suitable for various bonds of casting mold
