Introduction: With the continuous advancement of industrial technology, the refractory materials industry is undergoing new changes. In recent years, electric fused magnesia-alumina spinel and electric fused white corundum have become important raw materials in high-temperature industries due to their excellent physical and chemical properties, promoting the technological upgrading and application expansion of refractory materials. Body: Electric fused magnesia-alumina spinel is a high-purity ceramic material composed of magnesium oxide (MgO) and aluminum oxide (Al₂O₃), with extremely high refractoriness, thermal stability, and resistance to erosion. It is widely used in high-temperature industries such as steelmaking, glass, and cement, as a main component of furnace linings, kiln furniture, or castables. Electric fused white corundum is a high-purity refractory material mainly composed of aluminum oxide, characterized by high hardness and wear resistance, often used in the production of refractory bricks, abrasives, and precision casting sand. Against the backdrop of stricter environmental policies and rising energy costs, enterprises are increasingly demanding higher performance from refractory materials. Electric fused magnesia-alumina spinel is favored by more high-end users due to its good thermal shock stability and low thermal expansion coefficient. At the same time, electric fused white corundum, with its high purity and excellent mechanical properties, holds an important position in high-performance refractory products. In recent years, many domestic refractory material companies have increased their research and development investments in electric fused magnesia-alumina spinel and electric fused white corundum, optimizing production processes and enhancing product purity to further strengthen market competitiveness. Moreover, with the deepening promotion of intelligent manufacturing and green manufacturing concepts, the application scenarios of these materials are continuously expanding, extending from traditional industries to emerging fields such as new energy and aerospace. Conclusion: As core raw materials in the refractory materials industry, electric fused magnesia-alumina spinel and electric fused white corundum are driving industrial upgrading with their outstanding performance. In the future, with continuous technological innovation and changing market demands, these materials will play an important role in even broader fields, contributing to high-quality industrial development.
