ABSTRACT:
The invention includes methods of forming an aluminum oxynitride-comprising body. For example, a mixture is formed which comprises A:B:C in a respective molar ratio in the range of 9:3.6-6.2:0.1-1.1, where “A” is Al2O3, “B” is AlN, and “C” is a total of one or more of B2O3, SiO2, Si—Al—O—N, and TiO2. The mixture is sintered at a temperature of at least 1,600° C. at a pressure of no greater than 500 psia effective to form an aluminum oxynitride-comprising body which is at least internally transparent and has at least 99% maximum theoretical density.
