Driect nitridation of aluminum (known as "Geuther process") is one of the main mutes for synthesizing AIN. Another method is the carbothermal-reduction and nitridation (known as "Serpek process"); though it is better in many ways, problems still exist to be solved, e. g. since ml<sub>2</sub>O<sub>3</sub> is hard to be homogeneously mixed with carbon and because of its poor reactiveness, 展开更多
