Cyclic oxidation rates of 95 to 97 pct dense, powder-source molybdenum disilicide (MoSi2) in dry air, wet air, and oxygen have been measured between 400°C and 600°C. Dense MoSi2 does not disintegrate catastrophically (pest) in these atmospheres for exposure times up to 688 hours. Between 400°C and 500°C, Mo and Si oxidize simultaneously to form amorphous SiO2, monoclinic Mo9O26, and vapor-deposited MoO3 plates, and the oxidation rate of MoSi2 in air is influenced by its microstructure… CONTINUE READING
