Raw material effect on AIN powder synthesis from Al2O3 carbothermal reduction
- 151 Downloads
The effect of starting Al2O3 raw materials on the synthesis of AIN powder by Al2O3 carbothermal reduction was investigated. The reactivity ofγ-Al2O3 among other materials, is excellent, at 1500° C. The skeleton of raw powders remains in the AIN particle shape. The thermal conductivity for hot-pressed AIN was severely affected by the oxygen content in AIN powder.
