粉体晶粒的形成经历了“溶解一结晶”两个阶段：首先原料在热介质里溶解，以

The formation of powder grains has gone through two stages of "dissolution-crystallization": first, the raw materials are dissolved in the heat medium, enter the solution in the form of ions and molecular groups, and use strong convection to transport and release these ions, molecules and ion groups A saturated solution is formed in the growth area (low temperature area) of the seed crystal, and then nucleation, growth, and crystallization.
