| Abstract: | Under nitrogen atmosphere, the AlON powder was synthesized at normal pressure via high temperature solid state reaction using α-Al_2O_3 and AlN as raw materials. The influences of compositions, sintering temperature and holding time on the content of synthesized AlON powder have been investigated. Besides, the changes of heat flow and mass variation in synthesis process were tested by thermal analysis. The results showed that when the mass ratio of Al_2O_3 to AlN was up to 81:18, sintering temperature kept at 1750 ℃ and the holding time lasted 2 h, the content of AlON phase in the power synthesized could reach over 95%. |
