In order to prepare calcium nitrate crystals,the crystallization and moisture absorption properties of calcium nitrate were studied.The experimental results show that the crystallization effect of the crystallization temperature of 2.00℃,and the concentration ratio of 1.50.Calcium nitrate was placed in different temperatures,moisture at 10℃,but dehydrated at 20,30 and 40℃.Different crystalline water content of calcium nitrate,the lower the initial moisture content,the faster the moisture absorption speed of calcium nitrate,and the greater the total moisture absorption.However,when the moisture content reaches a certain level or is left for a certain period of time,its water absorption rate is basically the same,and the moisture content remains basically unchanged.
