AIN纳米微粉的微波合成

Nanometer aluminum nitride powder with purity higher than 98wt% and diameter in the range of 5-80nm has been obtained by microwave heating using α-Al2O3、Al(OH)3、 colloidal Al(OH)3 as the source for aluminum, and phenolformaldehyde resin, char, nanometer carbon black powder as the source for carbon, respectively. The effect of the type of starting materials and synthesis conditions on the purity and the size of the nanometer AlN powder has been analyzed in this paper.     

AlN纳米微粉的微波合成

AIN陶瓷作为一种新型的陶瓷材料，具有优异的力学性能、导热性能、电绝缘性能、抗氧化性能和机加工性能．其突出优点是具有高的热导率和低的热膨胀系数，在电子工业领域有着重要的用途．目前，制备AIN粉末的方法很多［l，2］，但用微波加热法合成AIN粉末尚未见文献报导，本文就
