AlON透明陶瓷的制备及其力学性能研究
Preparation and Mechanical Properties of AlON Transparent Ceramics
摘要
Abstract
AlON transparent ceramics have broad application prospects in national defense and civil use due to its good light transmission,thermal shock stability,mechanical properties and good processability.The AlON powder were prepared in batches by an improved carbothermal reduction nitridation/fluidized bed method in this article.A single batch can prepare up to 2 kg,and no second phase was observed in the XRD patterns of AlON powder.Laser particle size analysis shows an average particle size of 1.54 μm and the particle size distribution is uniform.Green body with good uniformity and high density was obtained using the powder molded by cold isostatic pressing.AlON transparent ceramics with transmissivity of 82.3%and bending strength of 310 MPa were prepared by sintering temperature at 1 850℃and nitrogen pressure of 5 MPa,which has certain practical significance for promoting the application of AlON transparent ceramics.关键词
