Spherical yttrium aluminum garnet powder and method for in-situ synthesis of spherical yttrium aluminum garnet powder through spray granulation technology
The invention relates to the field of inorganic powder preparation, and provides a method for in-situ synthesis of spherical yttrium aluminum garnet powder through a spray granulation technology, and the method comprises the following steps: S1, mechanically stirring yttrium oxide (Y2O3) powder, aluminum oxide (Al2O3) powder, deionized water, a dispersant and a binder to obtain mixed slurry; s2, performing spray granulation on the mixed slurry to obtain spherical mixed powder; and S3, putting the spherical mixed powder into a muffle furnace, and carrying out pressureless calcination in an air atmosphere. The method is simple in process, low in cost and energy consumption, high in yield, free of environmental pollution and suitable for large-scale industrial production.
本专利涉及无机粉体制备领域的一种提供了一种通过喷雾造粒技术原位合成球形钇铝石榴石粉体的方法，包括下述步骤：S1、将氧化钇(Y2O3)粉末、氧化铝(Al2O3)粉末、去离子水、分散剂、粘结剂进行机械搅拌，得到混合浆料；S2、将混合浆料进行喷雾造粒，得到球形混合粉体；S3、将上述球形混合粉体置于马弗炉中在空气氛围下无压煅烧。该方法工艺简单，成本及能耗低，产量高，无环境污染，适用于大批量工业化生产。
