摘要：NOVELTY - Preparation of mesoporous magnesium silicate comprises preparing mixture of P123 (RTM: poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) triblock copolymer) and water, adding hydrochloric acid, uniformly mixing, adding soluble magnesium salt, adding dropwise tetraethyl orthosilicate, stirring to obtain white turbid solution, continuously stirring to obtain sol-gel white emulsion liquid, aging, removing upper layer liquid, filtering, drying precipitate and sintering. USE - Method for preparing mesoporous magnesium silicate used for preparing calcium sulfate hemihydrate composite material for bone prosthesis (claimed). ADVANTAGE - The bone prosthesis has good biological activity and biological compatibility. It stimulates bone growth and healing. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of calcium sulfate hemihydrate composite material comprising mixing mesoporous magnesium silicate and calcium sulfate hemihydrate powder, stirring, molding, curing and drying.
