Abstract:

The oxidation behavior of MoSi2 dispersed with aluminosilicate was studied at 773 K. Aluminosilicate was dispersed into the grain boundary of MoSi2, and an oxide network was constructed without affecting its thermal shock property. The resulting MoSi2/oxide composites exhibited an excellent oxidation resistance at low temperatures.
