Study on the Crystallization and Moisture Absorption Properties of Calcium Nitrate
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.
