Abstract
An inorganic silicate-substituted calcium phosphate hydroxyapatite, useful as a biomaterial, has a Ca/P molar ratio in the range 2.05 to 2.55 and a Ca/(P+Si) molar ratio less than 1.66. The hydroxyapatite can be substantially free of carbonate ions. The material has relatively high solubility and is able to release silicon into solution.
