Powder mixtures based on calcium hydroxyapatite (HAP) and sodium dihydrophosphate are investigated. It is established that calcium phosphates with Ca : P = 1 are formed in these mixtures as a result of mechanochemical activation. On heating each component of the mixture undergoes a change: HAP (Ca : P = 1.67) partially transforms into tricalcium phosphate (Ca : P = 1.5), the low-temperature calcium phosphates brushite and monetite (Ca : P = 1) transform into calcium pyrophosphate, NaH2PO4 transforms into NaPO3, and Na2HPO4 transforms into Na4P2O7. In the process the components interact with one another with double sodium calcium ortho- and metaphosphates being formed.
