Ceramic Foundry Sand and Its Advantages
Ceramic Foundry Sand is a spherically shaped bauxite sand manufactured by melting bauxite in an Electric Arc Furnace followed by high pressure air blowing, screening etc. Ceramic foundry sand provides a unique combination of spherical shape particle, chemistry, and physical properties that result in numerous performance advantages compared with other foundry sands. Our Ceramic Foundry Sand performs very well comparatively to Chromite, and Zircon sands and has replaced these sands and Silica sand in many foundry and casting applications. The particle surface is much smoother than other foundry sands, leading to better castings.
