In this work we suggest a novel synthetic route combining Sol-Gel and SPS to fabrication of porous ceramics based on wollastonite with bimodal pore size distribution (100-500 nm and 1-500 µm) and high mechanical strength (Young’s Modulus from 72.5 to 172 MPa). We studied peculiarities of formation biporous silicate framework using two types of poreforming additives (templates) of various nature, shape and size, introduced during different stages of Sol-Gel and SPS synthesis: organo-nonorganic (polymer latex of “core-shell” type) and nonorganic (carbonaceous filler). The influence of carbonaceous template content (5 or 25%) on structural and mechanical properties of ceramics synthesized in the current of spark plasma was described. Original approach presented here provides formation of wollastonite ceramics of high mechanical strength with biporous structure that is similar to texture of bone tissue and is capable of executing its main functions. Obtained ceramics meets all the requirements of bioceramics class and is demanded by modern medicine.
