| titleOfInvention | Method for production of hydroxyl apatite |
| abstract | FIELD: technology of hydroxyl apatite production. SUBSTANCE: origin solutions of potassium nitrate and ammonium phosphate are neutralized by ammonia to pH 11. Hydroxyl apatite is added into solution of potassium nitrate, its quantity being 5-25 of stoichiometric quantity. Solutions are mixed, molar ratio of potassium and phosphorous being 1.67. Concentration of potassium nitrate and ammonium phosphate solutions during their mixing is 0.70-0.90 and 0.20-0.30 mol/l respectively. Precipitate is washed, dried and calcined to prepare desired single phase product. EFFECT: improves efficiency of the method. 1 tbl |
