MoSi2-oxide composites fabricated by using fine aluminosilicate powder (<0.2 μm) have demonstrated excellent low temperature oxidation and thermal shock resistance. Considering the heat-resistance characteristic of the MoSi2-oxide composites, the composition of 20 and 25 vol% oxide was selected and evaluated as a heating element being used for thermal treatment equipment of fast thermal processing(FTP). It is found that the working life(with 10% change of resistance) of low-temperature oxidation resistance of the composite is over 126 times of the MoSi2 heating element currently available on the market, and the life of the accelerated heating evaluation carried out repeatedly between 573-1673 K is above 110000 cycles. The working life of MoSi2-oxide composites can be expected sufficient as a heating element for thermal treatment equipment of FTP.
