Cheap Superior Quality Spinel Refractory Bricks for Sale
Magnesium aluminate spinel is a highly refractory material, with a melting point of 2135oC. Table 1 shows a comparison of the density, thermal expansion coefficient and thermal conductivity of the end-members (MgO, Al2O3) compared to the spinel phase. The differences between these phases in thermal expansion are responsible, in part, for
