Paper Title:
Setting Properties of Brushite and Hydroxyapatite Compound Cements
  Abstract

In this work properties of potential brushite (CaHPO4•2H2O) and hydroxyapatite (Ca10(PO4)6(OH)2) compound cements are investigated. Calcium dihydrogenphosphate monohydrate (MCPM) and α-tricalcium phosphate (α-TCP) were the starting materials for investigated cements. Setting time is controlled by adding setting time retarder – citrate ions and initially unreactive filler - monetite (CaHPO4). Some compositions of obtained cements contain both brushite and hydroxyapatite. However a substantial amount of monetite was present even if it is not added as filler. There is a strong evidence of presence of octacalcium phosphate – a precursor phase for hydroxyapatite that lacks long range order.
