FIELD: production of pure salts which may be used in medicine, gas chromatography, by production of paint and varnish, polymerization process. SUBSTANCE: method for production of hydroxyl apatite involves mixing of calcium hydroxide with phosphoric acid, settling, filtration and drying of desired product. Solution of calcium hydroxide being saturated at 25 C is mixed with solution of phosphoric acid, their molar ratio being 1.33-2.50. Proposed method is carried out at room temperature. Yield of desired product is 100 %. EFFECT: improved safety of the method; simplified the process for production of desired product.
