a Schematic illustration of the synthesis route for the S-MB ceramic composites. The synthesis involves (1) pre-treatment of multi-borides to reduce the surface B2O3 layer, (2) mixing and cross-linking of the pre-treated powders with a PDC-SiOC precursor, (3) mechanical processing into a green body, and (4) high-temperature pyrolysis to obtain the final S-MB ceramic composites. b XRD pattern of S-MB ceramic composites with different absorber contents. c SEM and corresponding elemental mapping images of S-MB-A. d BSE image. e CT analysis of S-MB-A, where black represents the S-MB-A sample, blue corresponds to the PDC-SiOC phase, pink indicates the pores, and red shows the multi-borides.
