Abstract

Al₁₈B₄O₃₃ is a binary compound formed in Al₂O₃-B₂O₃ systems, which has excellent properties such as hierarchical pore structure, lightweight, and high adsorption. In this study, Al₂O₃ and H₃BO₃ were used as the raw materials to prepare ceramic samples via extrusion-based 3D printing. The solid content of the ceramic slurry and sintering temperature were investigated. In addition, to further evaluate the potential biological applications of the porous material, biocompatibility experiments were conducted. The results show that the bending strength ranging from 8.71 to 40.63 MPa and the apparent porosity between 47.65 % and 55.33 %. And the prepared ceramic scaffold not only possesses significant protein adsorption capacity, but also promotes the adhesion and distribution of cells on its surface. This highlights the potential application of the Al₂O₃-B₂O₃ Scaffolds prepared in this study in the field of tissue engineering and regenerative medicine.

期刊介绍： The Journal of the European Ceramic Society publishes the results of original research and reviews relating to ceramic materials. Papers of either an experimental or theoretical character will be welcomed on a fully international basis. The emphasis is on novel generic science concerning the relationships between processing, microstructure and properties of polycrystalline ceramics consolidated at high temperature. Papers may relate to any of the conventional categories of ceramic: structural, functional, traditional or composite. The central objective is to sustain a high standard of research quality by means of appropriate reviewing procedures.
