Способ относится к химии фосфорсодержащих соединений кальция и может быть использован в качестве медицинского материала для стоматологии, а также адсорбента и катализатора. Способ позволяет получить продукт высокой степени чистоты очисткой исходных концентрированных растворов нитрата кальция активированным углем марки "А" и гидрофосфата аммония пропусканием через катионит КУ - 2 с последующим подщелачиванием концентрированным аммиаком очищенных растворов нитрата кальция до pH = 12,0 oC 12,5 и гидрофосфата аммония до pH = 10,5 oC 11,5 и кипячением в течение 30 - 90 мин образовавшейся суспензии.The method relates to the chemistry of phosphorus-containing calcium compounds and can be used as a medical material for dentistry, as well as an adsorbent and catalyst. The method allows to obtain a product of high purity by purifying the original concentrated solutions of calcium nitrate with activated carbon of grade "A" and ammonium hydrogen phosphate by passing through the cation exchanger KU - 2 with subsequent alkalinization of concentrated solutions of calcium nitrate to ammonium with pH = 12.0 o C 12.5 and hydrogen phosphate ammonium to pH = 10.5 o C 11.5 and boiling for 30 - 90 minutes the resulting suspension.
