Porous calc silicate bioceramic material, preparation method and application
The invention discloses a porous calc silicate bioceramic material, a preparation method and application. The porous bioceramic material comprises the following components in an oxide form in percentage by weight: 44 to 52 percent of CaO, 47 to 54 percent of SiO2, 0 to 3.0 percent of B2O3, 0 to 3.4 percent of ZnO and 0.2 to 4.8 percent of MgO, wherein the content of B2O3 and ZnO is not simultaneously 0; the ratio of the content of MgO and the content sum of B2O3 and ZnO is 1:(0.2-5). The preparation method comprises the following steps: preparing boron, zinc and magnesium-containing calc silicate superfine powder by using a wet-chemical method and a sol-gel method, preparing a porous material of which the shape is consistent with that of a skeleton of each part of a human body and the pore passage size is 80 to 800[mu]m by using a three-dimensional printing technology, and performing high-temperature sintering treatment. The material can be applied to the bone defect repair and bone regeneration medicine of the department of orthopedics, department of stomatology, plastic surgery, maxillofacial surgery, thoracic surgery department or ophthalmology department.
