## Abstract Interconnection, one of the main structural features of macroporous calciumβphosphate ceramics, contributes to the biological and physicochemical properties of bone substitutes. As no satisfactory method exists for evaluating this feature, analysis was performed to determine the permeab
The thermal stability of calcium hydroxyapatites (CaHAp) as prepared by traditional methods is quite low, with the preponderance of CaHAp being converted to Ca 3 (PO 4 ) 2 at temperatures as low as 973 K. In contrast, control of the pH during preparation markedly enhances the thermal stability of Ca
An in vitro study of the influence of Biphase Calcium Phosphate Ceramics (BCPCs) on bacteria1 strains is presented. The test procedures were carried out in saline test solution to which different quantities (2,4,50,100, and 200 mg) of BCPCs(samp1es A and B) were added. The influence of BCPCs on stan
