REACTIONS OF CARBIDES WITH GASES AT ELEVATED TEMPERATURES. PART I. BEHAVIOUR IN OXIDISING ATMOSPHERES

Technical Report ·
OSTI ID:4340183
Sintered compacts of the carbides cf titanium, zirconium, niobium, tantalum, vanadium, chromium, and boron were tested for oxidntion resistance in air. Zirconium, niobium, tantalum and vanadium carbides have a high rate of oxidation in air at 800 deg C. Chromium carbide has a very low rate of oxidation at temperatures up to and including 1000 deg C. At 900 and 1000 deg C titanium carbide has a linear oxidation rate which is probably too high for practical applications in oxidizing atmospheres. The oxidation of boron carbide in the range 900 to 1000 deg C is complicated by the volatilization of boric oxide, one of the oxidation products. (auth)
