The aim of this work is the investigation of alpha-tricalcium-phosphate (alpha-TCP) formation from calcium-deficient hydroxyapatite (CDHAP), synthesized by hydrothermal method from CaCl2, EDTA, NaH2PO4 center dot 2H(2)O and urea as precursors at 160 degrees C. Further, the influence of Ca/P ratios in the starting solution on alpha-TCP formation and the settings of obtained cements in simulated body fluid (SBF) were investigated. According to the results of X-ray, FTIR and SEM analyses, it is shown that CDHAP is transformed to beta-TCP at 800 degrees C, and to alpha-TCP at 1200 degrees C. Almost complete transformation of CDHAP into alpha-TCP occur after heating at 1500 degrees C in the case when Ca/P ratio in starting solution was 1,42. Cement powder mixed with the cement liquid (2.5 wt.% solution of Na2HPO4) completely hydrolyzes after 7 days in SBF, forming only CDHAP phase.
