Abstract
Novel compositions are provided for the production of hydroxyapatite, where a dry mixture is provided which combines a calcium source and an acidic phosphate source, particularly monocalcium phosphate monohydrate or orthophosphoric acid crystals. These two are combined, optionally with other ingredients, with mechanical mixing, resulting in partial reaction or intimate combination to produce a product which requires less water for formation of a desired viscosity, has enhanced mechanical properties and is physiologically acceptable.
