The preparation of multiphase ceramics in the CaO - P 2 O 5 system from mixtures of hydroxyapatite and monetite powders synthesized from calcium nitrate and ammonium hydrogen phosphate has been investigated. Monetite CaHPO 4 was used as a source of the resorbable phase of the composite ceramics - calcium pyrophosphate. It was found that during firing, a solid-phase reaction of interaction between HAP and PPA proceeds with the formation of TCP. Tab. 4, ill. 5, bibliography: 11 titles.
