Chromite foundry sand, with its main chemical component Cr2O3, boasts thermal stability, high thermal conductivity, and excellent resistance to alkali slag. It prevents metal penetration and sand sticking, making it ideal for various stainless steel, alloy steel, and carbon steel core-making applications.
Bubble alumina is a new type of high-temperature insulation material, consisting of a-Al2O3 microcrystals.
White fused alumina is produced from high-quality aluminum oxide powder, refined and crystallized through electric arc smelting.
Brown fused alumina is produced by melting high-quality bauxite, iron filings, and anthracite in an electric arc furnace at high temperatures.
Zirconia fused alumina is produced by melting aluminum oxide and zirconium oxide in an electric arc furnace at temperatures above 2000°C.
