| 摘 要： | 以Al（NO3）3和CH3OH为反应原料，经超声雾化后与NH3在高温下制备AlN（氮化铝）颗粒，X射线显示所得到的AIN颗粒具有六方晶体结构，通过扫描电子显微镜（SEM）对制备的颗粒的形貌及尺寸分布进行分析，制备的AlN颗粒呈现的是类似球状的形貌，直径约在100～200nm，并且对不同前驱体制备的AlN粉末的形貌进行了分析，找到了能够制备类球状AlN粉末相对较好的前驱体溶液。

| Abstract: | At high temperature and under ammonia atmosphere,a novel method,ultra-atomizing the precursor which was prepared by dissolving the aluminum nitride into methanol,was developed to synthesis large scale spherical aluminum nitride particles with a uniform diameter distribution from 100 to 200 nm,XRD pattern of the product indicated that the particles was hexagonal aluminum nitride;SEM was used to investigate the morphology and the diameter distribution of the ALN particles prepared in different conditions.The ... |
