Zirconia fused alumina is produced by melting aluminum oxide and zirconium oxide in an electric arc furnace at temperatures above 2000°C. It typically contains 10%-40% zirconium dioxide (ZrO2) and exhibits high toughness, dense structure, high strength, and good thermal stability, usually appearing in gray-brown color.
Chromite foundry sand, with its main chemical component Cr2O3, boasts thermal stability, high thermal conductivity, and excellent resistance to alkali slag.
Tabular alumina is a pure sintered alumina, thoroughly calcined without the addition of any additives such as MgO or B2O3. It boasts a coarse, well-developed α-Al2O3 crystal structure, with an Al2O3 content exceeding 99%.
Ceramic foundry sand is made from high-quality calcined bauxite, processed through electric fusion, granulation, and screening processes to produce spherical refractory particles.
Glass beads, produced from crushed glass and flat glass materials, are processed into spherical shapes through high-temperature melting.
