CALCIUM CHLORIDE FUSED
HS CODE 28272000
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:
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.
