Abstract: With KOH, H3BO3 and CaCl2·2H2O as raw materials,K2O·CaO·4B2O3·12H2O crystal was prepared by water solution method which is easily industrialized and pollution-free. Under the condition of 20 ℃, the crystallization process of K2O·CaO·4B2O3·12H2O crystals was studied, and in consequence, the crystallization kinetics equation and the relevant reaction rate equation were obtained.
