CALCIUM CHLORIDE FUSED AND POWDER

Calcium Chloride Fused

The wording Calcium Chloride fused is loosely used for Calcium Chloride having various amount of water with CaCl2 around its dihydrate  formula i.e. CaCl2-2H2O and it is ideally having 75.5%  Calcium Chloride with water as shown below:

CaCl2-2H2O
Ca(40) +  Cl2(71) + 2H2O(36) make % of CaCl2 in it as 36/(40+71+36) = 75.51%

It is important for the user of Calcium Chloride fused to understand this'

First stage at which manufactured Calcium Chloride, CaCl2 is available is of Calcium Chloride Solution say of 30-35%. On further evaporation it can be converted to Calcium Chloride Dihydrate Crystals or Calcium Chloride Fused.

Calcium Chloride Dihydrate is having a melting point of 176C or there about. When its solution is evaporated in bottom fired open pans. There is a percent gradient in the mass due to bottom heating and top cooling. The material becomes fluffy and semi-solid at about 72% CaCl2. If the material is discharged at this point we can call this material as Solid Fused Calcium Chloride.

If the evaporating solution is not discharged at a little over 72% assay. It evaporates further to a mass at >176C and solidifies when the assay is >77%. If the material is discharged at this point we can call this material as Porous Fused Calcium Chloride.
