CSIR-CGCRI, India (2000) PROCESS FOR THE PREPARATION OF SINTERED CUBIC GAMMA-ALUMINIUM OXYNITRIDE. IN226271.

Full text not available from this repository.

Abstract

A process of preparing dense cubic gamma-aluminium oxynitride spinel is provided comprising the steps of reaching alpha-Al O and AlN 2 3 in nitrogen atmosphere without the use of external additive, breaking down the resulting agglomerate into powder, further sintering the precompacted powder in nitogen atmosphere into substantially homogeneous dense product of density >98% theoretical with an inline transmission of at least 10% in the 0.3 to 5 μm wavelength spectral region.
