Abstract
Conclusions
From the standpoint of solubility in hydrochloric acid solutions of the concentration and at the temperature of gastric juice, unrefined dicalcium phosphate is greatly superior to bone meal. The calcium and phosphorus of unrefined dicalcium phosphate are also more available than these elements in the form of tricalcium phosphate. Refined dicalcium phosphate bears a similar relation to these salts as unrefined dicalcium phosphate does, although the solubility figures for the latter are slightly higher.
