METHOD OF PREPARING FINELY DISPERSED SINGLE-PHASE HYDROXYL APATITE Russian patent published in 2001 - IPC

FIELD: manufacture of composite materials bioceramic products, sorbents and catalyst. SUBSTANCE: method comprises preparing finely dispersed single-phase hydroxyl apatite, synthesizing calcium phosphate, mixing solution thereof with alkali till pH value of 10-20 is adjusted, separating, washing and drying product residue at temperature of not higher than 60 C. In this case, synthesized calcium phosphate solution is pretreated with alcohol at calcium phosphate solution to alcohol volumetric ratio of 1:0.001-1, and mixing is carried out with aqueous alcoholic alkali solution having aqueous alkali solution to alcohol volumetric ratio of 1:0.001-1 to produce finely crystalline hydroxyl apatite useful for biomedical, sorption and catalytic processes. EFFECT: more efficient preparation method.
