考察了初始溶液组成、PH 值、陈化温度及陈化时间对碱式碳酸钇均分散溶胶形成及颗粒尺寸的影响。观察了碱式碳酸钇颗粒灼烧成氧化钇后颗粒的形状及尺寸的变化。
The effects of initial solution composition, PH value, aging temperature and aging time on the formation and particle size of basic yttrium carbonate dispersed silica sol were investigated. The changes of the shape and size of the particles after the basic yttrium carbonate particles were fired into yttrium oxide were observed.
