Dibasic calcium phosphate, CaHP04, is also called calcium monohydrogen phosphate, dicalcium orthophosphate, or secondary calcium phosphate. It is usually found in the form of hydrate, such as CaHP04 2H20. It does not melt, instead decomposing when heated to 109°C (228°F).

Dibasic Calcium Phosphate is a white odorless, tasteless powder or crystalline solid prepared from a phosphate mineral such as apatite. The apatite is dissolved in sulfuric acid and then filtered. The addition of calcium hydroxide precipitates dibasic calcium phosphate. The USP lists two types of calcium phosphate dibasic calcium phosphate, anhydrous, which has the empirical formula of CaHP04, and dibasic calcium phosphate dihydrate which has the empirical formula CaHP04 2H20. Synonyms for dibasic calcium phosphate include calcium hydrogen orthophosphate, dicalcium orthophosphate, and secondary calcium phosphate.

In internal or bulk settiag, which is normally carried out at room temperature, the calcium is released uader coatroUed coaditioas from within the system. This method led to the developmeat of stmctured fmits, stmctured pet foods, and a host of cold prepared desserts. Calcium sulfate (usually as the dihydrate) and dicalcium phosphate (calcium hydrogen orthophosphate) are the sources of calcium most commonly used. 

The disadvantage of the polyphosphates is that at the temperatures (100 °C or higher) used in many textile processes they can be hydrolysed into simpler phosphates that cannot retain the metal atom in the sequestered form. For example, dicalcium disodium hexametaphosphate hydrolyses on prolonged boiling to yield the insoluble calcium orthophosphate. This is one of the main reasons why polyphosphate sequestrants are used much less extensively than the more versatile and stable aminopolycarboxylates. 

Dietary inoiganic phosphates have been shown to piotect expeiimental animals against dental caries. Orthophosphates were effective cariostats, but NjuP Oj and NasPgOio were not. Dicalcium phosphate, CaHPCL. did not decrease dental caries unless a high level of NaCI was also included in the diet. 

Effect of Phosphorus on Human Metabolism of Iron and Zinc. Several groups of investigators have examined the effect of orthophosphate salts on iron and zinc utilization by human subjects. Peters, et al. (35) found that the oral administration of sodium orthophosphate salts or dicalcium phosphate with a solution of radiotagged iron chloride and ascorbic acid reduced the retention of 5 Fe by human subjects (Table IV). However, Monsen Cook (36)...
