Abstract
Herein is disclosed a method of crystallization with the particle size distribution being controlled, characterized in that while crystals are being precipitated by vacuum concentration crystallization, the temperature of the slurry is periodically varied up and down during the concentration of the crystallization mother liquor (i.e., the slurry), which method is an excellent one free from the defects of the conventional methods.
