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

Abstract RU 2362730 C2

FIELD: nanotechnology.

SUBSTANCE: invention relates to method of receiving of nano-crystalline hydroxyapatite. According to the invention calcium nano-crystalline hydroxyapatite is received by interaction of compound of calcium and ammonium hydro-phosphate. In the capacity of calcium compound it is used sugar lime C₁₂H_22-2nO₁₁Ca_n, at n, which is situated in the range from 0.5 up to 2. Particles size of the received hydroxyapatite is 30-50 nm.

EFFECT: receiving of nano-crystalline powder of calcium hydroxyapatite, which contains unaggressive biocompatible accompaniment of the reaction and that provides its usage in medicine.
