High temperature oxidation of tantalum carbide powder
The high-temperature oxidation of tantalum carbide (TaC) powder was investigated to determine the application of refractory materials for space crafts. TaC powder with an average particle size of about 10 Jim was used in this experiment. The samples were oxidized in air at 573 to 1273K for 5 min to 25 h. The weight changes were measured to estimate the oxidation properties. Exposed for short oxidation times of 5 min, started at 873K, and weight changes increased with increasing oxidation tempera
