气溶胶反应器分解叠氮二乙基铝制备氮化铝纳米粉体

Aerosol Sythesis of Aluminum Nitride Powder Using Diethylaluminun Azide

    摘要
  • 摘要: 以叠氮二乙基铝(CH3CH2)2AIN3为前体物在气溶胶反应器中热分解制备氮化铝AIN纳米粉体.单反应物且无载气使反应器简化.分解温度低于500-700℃.所得球状AIN纳米粒子平均粒径为10-50 nm,表面积为103m2/g,活性高.该法为AIN纳米粉体的合成找到了一条新途径.

     

    Abstract: A aerosol process is described for making nanometric Aluminum Nitride powder by pyrolysis of single compound Diethylaluminun Azide.The process can produce spherical A1N powder with mean particle diameter ranging from 10 to 50 nm at the temperature of furnace as lower as 500-700. The generated amorpous AIN powder is characterized by a BET surface area of 103m2/g and is very reactive toward moisture. A new way of preparing nanometric powder of AIN is found.
