Zirconia Corundum is a high-performance refractory material produced by fusing zirconia and alumina in electric arc furnaces above 2000°C, resulting in a dense, crystalline structure composed of zirconium oxide and aluminum oxide. This process yields a material with superior refractory qualities such as a high melting point, excellent thermal shock resistance, and low thermal expansion. Its resistance to chemical attack from molten metals and slag makes it ideal for harsh environments, establishing it as a durable, versatile, and reliable material in refractory applications.
