| 摘 要： | 液相法合成陶瓷粉科有利于成分的精确控制和均匀混合，可制备颗粒微小、尺寸均一的粉料。但是从液相中制粉容易引起因粉料团聚而使粉料丧失超细粉料的优点。本文分析了固相颗粒在液相中的生长过程，讨论了均一尺才颗粒的生长条件，论述了液相法合成陶瓷粉科中形成团聚的3个过程，以及各种控制团聚的工艺方法和避免团聚的工艺措施。

| Abstract: | Liquid synthesis of ceramic powders has some advantages, including precise control of chemical composition and its homogeneity, easy control of particle size and easy obtaining narrow size distribution. However, liquid synthesis may result in severe agglomeration in the powders, which degrades the processing properties of the synthesised powder. The mechanism of formation of solid particles from liquid and the requirement for formation of monedispersed particles are discussed. Three mechanisms of formation of agglomerates during synthesis of powders and the measures to ease off the problems are also discussed. |
