摘要/Abstract

摘要： AlON透明陶瓷因良好的透光性、热震稳定性、力学性能和良好的可加工性,在国防领域和民用领域有广阔的应用前景。本文采用改进的碳热还原氮化/沸腾床法批量制备AlON粉体,单批次产能可达2 kg,在AlON粉体的XRD图谱中未观察到第二相,激光粒径分析显示平均粒径为1.54 μm,粒径分布均匀。使用该粉体进行冷等静压成型处理后,获得均匀性较好、致密度高的素坯。采用气压烧结法在1 850 ℃,氮气压力5 MPa下制备出光学透过率为82.3%,弯曲强度为310 MPa的AlON透明陶瓷片,对推进AlON透明陶瓷的应用具有一定的现实意义。

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.

Key words: AlON, carbothermal reduction nitridation method, high-purity powder, transparent ceramics, transmittance, gas pressure sintering
