Synthesis and Study of the Properties of Corundum-Mullite

The conditions for the synthesis of mullite-corundum ceramic prepared on the basis of Al 2 O 3 and SiO 2 powders were investigated. The composition of mullite-corundum ceramic with Al 2 O 3 < 80 wt.%, which affords the best thermomechanical compatibility with molybdenum, was determined. The possibility of obtaining a composite material based on a …
