DiCalcium Phosphate

Alternate Names: Dicalcium Phosphate Anhydrous

Description: Synthetic Bone Ash, Di-Calcium Phosphate

Oxide Analysis Formula
CaO 40.63% 0.67
P2O5 51.38% 0.33
LOI 8.00%n/a
Oxide Weight 84.70
Formula Weight 92.06


An anhydrous white, odorless, tasteless powder. It is stable in air and insoluble in water and alcohol but readily soluble in hydrochloric and nitric acids. It is used in the food industry as a mineral supplement and dough conditioner. Dicalcium phosphate dihydrate is similar (CAS# 7789-77-7).

Dicalcium phosphate can be used in glazes as a source of calcium, however, other sources are much less expensive and more practical. Tri-Calcium phosphate is considered a better substitute for bone ash in ceramics than is this material.

LOI is 7-8.5%
Bulk density is 83 lbs/cubic foot
