Abstract
Cast aluminum oxynitrides were prepared by aluminothermic SHS under pressure of nitrogen gas and characterized by time-resolved XRD and chemical analysis. Burning velocity U, material loss caused by sputtering η1, and yield of target material into ingot η2 were measured as a function of nitrogen pressure P(N2). The nitrogen content of synthesized oxynitrides was made as high as 7 wt %. The results may turn helpful in designing high-strength transparent ceramics.
