Abstract

Abstract: Based on experiments,the nucleation and growth process of crystal grains in the reaction process was investigated.The influence of oxidation rate during the earlier period in the reaction process on the parameters of the final crystal grains was surveyed.The improvement of the final product by aging techniques was also reported.
