METHOD OF RECEIVING POWDER OF NANO-CRYSTALLINE CALCIUM HYDROXYAPATITE Russian patent published in 2009 - IPC C01B25/32 B82B3/00 

Abstract RU 2362731 C2

FIELD: nanotechnology.

SUBSTANCE: invention relates to method of receiving of powder of nano-crystalline calcium hydroxyapatite. Nano-crystalline calcium hydroxyapatite is received by interaction of calcium hydroxide and solution, containing phosphate-ions, herewith suspension of calcium hydroxide is prepared directly before interaction with solution, containing phosphate-ions from solutions of calcium acetate and potassium hydroxide, herewith amount of calcium hydroxide is from 50 up to 100% in mixture of calcium-bearing components.

EFFECT: receiving of hydroxyapatite powder with particles size 30 - 50 nm.
