Magnesium-Aluminum Spinel
Magnesium-alumina spinel is produced by melting industrial-grade alumina and high-purity caustic-calcined magnesium in an electric arc furnace.
Its high corrosion and thermal shock resistance, combined with its high-temperature strength properties, make it a valuable raw material for spinel steel, cement, and high-performance refractory applications.
KEY FEATURES
- Excellent corrosion resistance
- Excellent thermal shock resistance
- Good heat resistance
- Different chemical compositions and particle size distributions
APPLICATIONS
- High-performance refractory bricks
- Monolithic refractories
- Steel crucibles and high-temperature processes
