以硝酸盐水溶液为原料、高频感耦等离子体为加热源、超声雾化热解的方法制备CuO／Al2O3粉体．研究发现，溶液浓度及等离子体参数条件对粉体初始态的特性有很大影响，浓度越低；粉体越细．纯Al2O3粉为位径在1μm左右的空心球或壳状碎片，CuO粉由无定型海绵体与平均粒度为20nm的超细粒子组成．混合溶液制得的粉体形貌随着Cu／Al原子比的变化而变化，CuO与Al2O3熔点温度相差较大是导致杨体生成微观过程不同的主要原因．
The CuO / Al2O3 powder was prepared by using nitrate aqueous solution as raw material, high frequency inductively coupled plasma as heating source and ultrasonic atomization pyrolysis. The study found that the solution concentration and plasma parameters of the initial state of the powder have a great influence on the characteristics of the lower the concentration; the finer the powder. The pure Al2O3 powder is a hollow sphere or shell fragment with a diameter of about 1 μm. The CuO powder consists of an amorphous sponge and an ultrafine particle with an average particle size of 20 nm. The morphology of the powder prepared by the mixed solution changes with the atomic ratio of Cu / Al, and the difference between the melting temperature of CuO and Al2O3 is the main reason that leads to the different microscopic processes of the formation of the astronomers.
