Green silicon carbide is made from petroleum coke and high-quality silica, with salt added as an additive, and refined in a high-temperature resistance furnace.
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.
