In this paper the synthesis of bioactive cement based on al-Ca-3(PO4)(2) (a-TCP) and calcium deficient hydroxyapatite (CDHAp), obtained by hydrothermal method from CaCl2, EDTA, NaH(2)PO(4)(.)12H(2)O and urea at 160 degrees C, was described. According to the results of DTA, SEM, X-ray and FTIR analyses performed in this investigation, it is shown that CDHAp is transformed to beta-TCP at 780 degrees C, and to a-TCP at 1400 degrees C. The hardening of the samples, prepared from the mixture of alpha-TCP and 2.5 % solution of Na2HPO4, in simulated body fluid at 37 degrees C, was followed by the microstructure changes.
