Chromite Sand

Chromite Sand

 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.
