Abstract: It has been established that xerogels of basic and medium calcium phosphates obtained by dehydration of calcium phosphate gels in air at 20°C with water-removing agents, cryogenic treatment (at −18 and −196°C) are characterized by a high specific surface (up to 158 m2/g). It was found that high-temperature heating of calcium phosphates at 800−1200°C leads to a significant decrease in their adsorption capacity (ABET 10−17 m2/g).
Keywords: calcium phosphate xerogel, adsorption-structural properties, hydroxyapatite, tricalcium phosphate, brushite, carbonate hydroxyapatite.
