Preparation of Transparent AlON Ceramics Using Single-Phase Powder Obtained from Carbothermal Reduction
Single-phase AlON powder was prepared by carbothermal reduction in flowing nitrogen atmosphere, using nano-sized alumina and carbon powder as raw materials. Transparent AlON ceramic samples using the single-phase powder were prepared by sintering at the temperature of 1880°C for 10h, 20h and 40h in flowing nitrogen atmosphere, respectively. It showed that the transparency and the density of the ceramic samples increased with increasing temperature holding-time. And the microstructures of the obtained samples were observed.
