摘要：
The properties of Ca-deficient hydroxyapatite powder synthesized from calcium nitrate and ammonium hydrophosphate at 60 degrees C, pH = 7, and Ca/P = 1.67, 1.61, and 1.48 are presented. After sintering at 1100 degrees C for 6 h the phase composition of the ceramic based on these powders was represented by tricalcium phosphate ( Ca/P - 1.48) or tricalcium phosphate hydroxyapatite ( Ca/P - 1.67 and 1.61). The grain size of the ceramic was 100 - 1000 nm.
