ABSTRACT:
A silicon carbide powder consisting of an aluminum component such as aluminum nitride and aluminum oxide and a chromium component such as chromium carbide as essential ingredients and if desired, a rare earth element such as yttria is sintered into an integrated molded article. This sintered article has excellent strength and toughness and a markedly reduced tendency to undergo corrosion when brought into contact with iron at high temperatures.
