23 Jul METHOD OF MAKING CALCIUM-PHOSPHATE GLASS FIBRE MATERIALS
Abstract
FIELD: process engineering.SUBSTANCE: invention relates to medicine. Proposed method can be used in stomatology and orthopedics for production of medical materials stimulating recovery of bone tissue defects, for making dental stopping and dental pastes. It comprises preparation of mix containing compounds of calcium, phosphorus, silicon and sodium, impregnation of bioinertial incombustible porous matrix with made mix, matrix is composed of ceramics from aluminium or zirconium oxides followed by calcination. Note here that silicon compound represents tetraethoxysilane. Note also that phosphoric acid ether is used as phosphorus compound. Calcium and sodium compounds are represented by their carboxylates in polar organic solvent. This method includes making the thin layers on more strong bioinertial porous ceramics. Note also that said process involves no special complicated equipment and expensive reagents.EFFECT: production of glass ceramics directly from solution omitting sol preparation stage, simplified and accelerated process.7 cl, 5 ex
