Magnesia–spinel (MgAl2O4) refractory ceramic composites
Jan 01 2006 · MgO-spinel refractory has better high temperature mechanical properties in arc furnace roof application compared to magnesia–chrome refractories but it has lower strength than a high-alumina refractory. High-density spinel refractory brick is made by calcining (1200–1300°C for about 3 h) compacted powders and then sintering at 1700°C.
