Preparation method of medical resilient calcium silicate porous ceramic scaffold
The invention discloses a preparation method of a medical rebounding calcium silicate porous ceramic scaffold, which comprises the following steps: synthesizing calcium silicate nanofibers, uniformly mixing the calcium silicate nanofibers with ice powder at the temperature of below 0 DEG C, compacting and molding, carrying out freezing point heat preservation recrystallization, freeze-drying and sintering to obtain the porous ceramic scaffold with a one-dimensional calcium silicate nanofiber framework, the calcium silicate porous ceramic support overcomes the brittleness of a ceramic material and has rigidity and resilience, in addition, ice powder is used as a pore-forming agent and is clean and pollution-free, the pore diameter can be adjusted by the particle size of the ice powder, and the pore channel connectivity of the porous ceramic support can be adjusted by heat preservation recrystallization of the ice powder at the freezing point. The porous ceramic shows high rigidity and resilience, and has a great application prospect in the field of biomedicine.
本发明公布了一种医用可回弹硅酸钙多孔陶瓷支架的制备方法，先合成硅酸钙纳米纤维，然后在0℃以下，将硅酸钙纳米纤维与冰粉混匀、压实成型、冰点保温重结晶、冻干、烧结，得到由一维硅酸钙纳米纤维架构的多孔陶瓷支架，本发明公布的硅酸钙多孔陶瓷支架，克服了陶瓷材料的脆性，具备刚性和可回弹性，另外使用冰粉为造孔剂，洁净无污染，且孔径可由冰粉粒径调节，多孔陶瓷支架孔道联通性可由冰粉在冰点的保温重结晶调节。多孔陶瓷表现出高刚度和可回弹性，在生物医学领域有较大应用前景。
