碳热还原氮化法合成AlON粉体的表征及透明陶瓷的制备
Characterization of the AlON Powders Fabricated by Carbothermal Reduction and Nitridation Method and Preparation of the Transparent Ceramic
摘要
Abstract
The gamma alumina and carbon black as raw materials were used to synthesize AlON powders through the carbothermal reduction and Nitridation method .And then transparent AlON ceramics were fabricated with the nano-micro AlON powders obtained by high energy ball -milling the synthesized AlON powders.The AlON powders were characterized with SEM , XRD, FTIR, electron energy-loss spec-troscopy(EELS), and Nitrogen /oxygen Determinator etc.The results show that the single phase AlON powders with an average particle size of 0.65 μm and a specific area of 12.6 m 2 /g were prepared by high energy ball-milling of the synthesized AlON powders .Compared with Al5 O6 N phase, the single phase powders have the similar Al content to a little higher oxygen content and lower nitrogen content .Using 0. 08wt％Y2 O3 +0.02wt％La2 O3 as the sintering aids, the transparent AlON ceramic with the in-line optical transmittance at 900 nm wavelength of 71.5％ (1 mm thickness) was prepared by pressureless sintering the AlON powders under the condition of 1875 ℃ ×24 h.关键词
