采用2种浆料结合三维凝胶叠层技术,成功制备了具有良好连通性的口.磷酸三钙支架,支架具有明显的叠层结构。采用固相含量为30%(体积分数,下同)的浆料制备坯体,1150℃下烧结2h得到的伊磷酸三钙支架,其垂直于叠层方向的抗压强度为(8.24±0.64)MPa,平行于叠层方向的抗压强度则为(25±3.4)MPa,具有一定的取向性。
Multilayer β-TCP scaffold was prepared by using three-dimensional gel-lamination technology with several kinds of slurries. Using 30% slurry as materials and sintered at 1150℃ for 2 hours, β-TCP scaffold with oriented structure was achieved which has the compression strength of (8.2±0.64) MPa in the orientation vertical to the layers while the compression strength of (25±3.4) MPa in the orientation parallel to the layers.
