Sintered Polycrystalline Nitrogen Stabilized Cubic Aluminum Oxide Material.

Abstract

This patent application covers a structural ceramic material comprising single phase polycrystalline cubic aluminum oxynitride preferably with at least 97% of theoretical density. It displays transparency and isotropic optical, thermal and electrical properties, an infrared cutoff at about 5.2 microns wavelength, and shows no chemical or physical property change after heating in air (atmosphere) at 1100 C.
