METHOD OF FABRICATING POROUS CERAMIC ARTICLES FROM β-TRIBASIC CALCIUM PHOSPHATE FOR MEDICAL APPLICATIONS Russian patent published in 2013 - IPC A61L27/10 A61L27/12 C01F11/00

Abstract RU 2481857 C1

FIELD: process engineering.

SUBSTANCE: invention relates to production of beta-tribasic calcium phosphate ceramic articles fur use as bone implants. Proposed method comprises the following steps: preliminary heat treatment of gypsum preforms for 2.0-2.5 hours, conversion of said gypsum preform in hydroxyapatite in 1-molecular solution of ammonium phosphate for, at least, 24 hours and further heat treatment at 970-1030°C.

EFFECT: hardness of, at least, 2,2 MPa.
