FIELD: chemistry; medicine.
SUBSTANCE: invention relates to chemical and medical industry, specifically to a method of producing amorphous tricalcium phosphate and can be used in production of initial biocompatible material. Method is carried out by depositing medium calcium phosphates formed when an aqueous solution of calcium chloride and diammonium phosphate is discharged and continuously stirred in excess ammonia, with subsequent filtration of obtained precipitate, its washing with water from chlorine ions and drying. Deposition is carried out at temperature of 20–25 °C for 10–15 minutes.
EFFECT: technical result consists in simplification of technology in obtaining tricalcium phosphate in amorphous form, which does not have irritant effect on skin, does not contain impurities.
