Paper Title:
Synthesis of MgAl2O4 Spinel-Corundum Composite with Waste Refractory
  Abstract

Magnesia-alumina spinel-corundum composite was prepared with waste slide plate and waste magnesia carbon brick. The magnesia-alumina spinel-corundum composites were investigated with XRD, SEM, DSC/TG. With the increasing amount of the waste slide plate used and increasing of synthesis temperature, the bulk density of the sample increase and the apparent porosity decrease, but the crystallinity of the sample decrease and the magnesia-alumina spinel phase increases. The obtained composite contained 72 wt % spinel, corundum 26 wt %. Primary and secondary phase were bonded by glass phase. The results shows that it is feasible to synthesis magnesia-alumina spinel-corundum material with waste slide plate and waste magnesia carbon brick.
