Production of dicalcium phosphate or monocalcium . 200126&ensp·&enspCalcium phosphate has a relatively low phosphorous content (20% m/m) while monocalcium phosphate, while having a much higher phosphorous content (26.5% m/m), is difficult to manufacture, and also expensive mainly because one of the byproducts of the reaction by means of which it is so prepared, …

Moreover, dicalcium phosphate production in China exceeded the figures recorded by the second-largest producer, Tunisia (X tonnes), threefold. The third position in this ranking was occupied by Peru (X tonnes), with an X% share. In China, dicalcium phosphate production remained relatively stable over the period from 2012-2021.

Tricalcium Phosphate (also known as TCP, Tribasic Calcium Phosphate and Bone Phosphate of Lime) belongs to calcium phosphate family of minerals and is mainly used in food industry as an anticaking agent in powdered spices, and as a nutritional supplement in baby powder. It is also used as cements, composites, and coatings, are used in many medical and dental applications.
