Analysis and Evaluation of the Comprehensive Property for Transparent Aluminum Oxynitride (ALON) Ceramics

摘要：

ALON ceramics with optimal mechanical and optical properties were obtained by cold isostatic pressing the as-prepared powders at 180 MPa and sintering at 1900℃ under N2 atmosphere for 8h. Microstructures and IR transmittance of ALON prepared under different sintering conditions were studied systematically to discuss the effect of microstructures on mechanical properties and IR transmittance. In addition,IR spectra of transparent ALON test pieces in different thickness were collected. The results demonstrated that the bending strength decreased while IR transmittance increased with the increase of grain size of ALON ceramics; with the increase of thickness of ALON test piece,IR transmittance decreased and the scope of the decrease reduced with the increase of grain size of ALON ceramics.
