Aerosol Sythesis of Aluminum Nitride Powder Using Diethylaluminun Azide
-
摘要: 以疊氮二乙基鋁(CH3CH2)2AIN3為前體物在氣溶膠反應器中熱分解制備氮化鋁AIN納米粉體.單反應物且無載氣使反應器簡化.分解溫度低于500-700℃.所得球狀AIN納米粒子平均粒徑為10-50 nm,表面積為103m2/g,活性高.該法為AIN納米粉體的合成找到了一條新途徑.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.
