Fused ceramic sand, also known as “ceramic foundry sand ’’, is a calcined bauxite with aluminum oxide ( Al2O3 ) as the main component, which is made by melting, blowing, screening and mixing.

In Sanmenxia Qiangxin Foundry Material Co., Ltd., workers added calcined bauxite ore containing 65 % -90 % Al2O3 to the arc melting device, and the ore melted into liquid at high temperature and then flowed out. At this time, the liquid was blown into fine particles with a certain pressure of compressed air. Under the action of surface tension, spherical or nearly spherical, smooth surface sand particles were obtained, and then cooled and sieved to obtain ceramic sand with different particle sizes, and then graded and packaged according to the particle size distribution required by the customer to become the final product of ' ceramic sand '.
