Fused Chrome Corundum
Fused Chrome Corundum is produced by melting high-purity alumina and chromium oxide in an electric arc furnace at ultra-high temperatures. The addition of Cr₂O₃ enhances corrosion resistance, thermal stability and wear resistance, making it an ideal raw material for advanced refractory and abrasive applications.
