Effect of phase transformations during synthesis on the chemical composition and structure of calcium-deficient hydroxyapatite

Biomaterial Based on Doped Calcium Carbonate-Phosphate for Active Osteogenesis

“…Methods of synthesizing calcium hydroxide phosphates are known. They consist in the following: precipitation from salts of calcium (or hydroxide, or oxide, or carbonate) with addition of о-phosphoric acid or mono-or double-substituted phosphate salts with the subsequent hydrolysis in the solution, under hydrothermal conditions, or as a result of pyrolysis [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. Methods for synthesizing calcium hydroxide phosphates are most exhausttively discussed in [4].…”
