Ceramic Foundry Sand Powder, also called Ceramic Foundry Sand Flour. Features： High refractoriness. Spherical shape. Low thermal expansion rate. Inert chemical performance. Intrinsic hardness and wear resistance. Good thermal conductivity. Applications Generally, Ceramic Foundry Sand Powder is popularly applied in foundry coatings and in 3D printing processes. 1. Applications in foundry coatings Ceramic Foundry Sand

Ceramic Foundry Sand, technically named as “Fused Ceramic Sand for Foundry”, also named as ceramsite, is good spherical grain shape which is made from calcined bauxite. Its main content is aluminum oxide, and it is processed by melting, blowing, sieving and blending. Ceramic sand, has much better properties than that of silica sand to gain

Fused Ceramic Sand is the custom ceramic particles with a spherical shape, high refractoriness and low thermal expansion being made by spraying the melted calcined bauxite. It provides a very simple but efficient way for the foundry-men to improving the quality of the castings, reducing the production cost and avoiding environmental pollution, because of that it

Ceramic sand , technically as fused ceramic sand for foundry, is made from calcined bauxite which main content is aluminum oxide, processed by melting, blowing, sieving and blending. Ceramic sand has excellent properties, including spherical shape, high refractoriness, good crush resistance, inert chemical characteristics, high reclamation yields, etc. To solve the problem of metal penetration

Pue to its unique physical and chemical properties,the sand has the following charateristics and advantages: Prevention of sand expansion defects,especially finning/veining Elimination of gas-forming additives Prevention of reactions between metal and moulding sand Prevention of metal penetration Reduction of core weight Improved flowability of moulding sand Influence on the formation of microstructure Pouring of thin-walled
