摘要：

The oxidation resistance of boron nitride samples obtained by various methods and having different crystalline structures has been studied by thermogravimetric, differential thermal and IR spectral analyses. The real structure of a material being oxidized is of the greatest importance for the steady-state process of high-temperature oxidation. Physico-chemical properties of the scale (B//2O//3 vaporization) impose limitations on the use of boron nitride-based materials in oxidizing media at temperatures higher than 1300 degree C.
