摘要

采用一种基于溶胶-凝胶法的快燃技术来合成钇铝石榴石(YAG,Y₃Al₅O₁₂)前驱体纳米粉体,并将其与传统溶胶-凝胶法所制样品进行比较。结果表明:两种方法获得的YAG物相纯度基本一致。但是,快燃技术合成的YAG粉末形状单一,颗粒之间的连接较为松散,以软团聚为主,且颗粒粒径偏差小,其平均粒度为63nm;而传统溶胶-凝胶法合成的YAG粉末形状非常不规则,种类繁多,颗粒之间的连接较为紧密,较多的呈现硬团聚的特征,且颗粒粒径也有较大的偏差,其平均粒度约为85nm。

Abstract

A process of fast combustion followed by sol-gel was applied to synthesize YAG nano-powders,and compared with another powders by conventional sol-gel method.It indicated that the purity of two kind powders were nearly coincident.On the other hand,YAG powder via sol-gel fast combustion method was dispersive and uniform.Nevertheless,its average size which had hardly disparity was about 63nm.But other powder average size which had a little disparity was approximately 85nm.
