How Different Between Anhydrous Calcium Chloride And Dihydrate Calcium Chloride?

- Jul 28, 2020-

Three differences between anhydrous calcium chloride and dihydrate calcium chloride


1. Existence form: Anhydrous calcium chloride and dihydrate calcium chloride are classified according to the molecular form of calcium chloride in the substance. There is basically no water in anhydrous calcium chloride, only a small amount of external water; each calcium chloride molecule in calcium chloride dihydrate exists in the form of two crystal waters, and the water content in the substance is relatively high.


2. Appearance: Anhydrous calcium chloride is generally spherical with a diameter of 2-6 mm, and calcium chloride dihydrate is generally flake with a thickness of 1-2 mm. Colors such as high purity are white, and low purity corresponds to lower whiteness.


3. Net content: The net content of calcium chloride in anhydrous calcium chloride is 90% or more than 94%, and the net content of calcium chloride in calcium chloride dihydrate is about 70%.
