[Display omitted] •Nano-whiskers based 3D Si3N4 porous ceramics (3D-NWSNPC) were prepared via a facile one-pot foam-gelcasting/nitridation route at 1423–1523 K.•3D-NWSNPC showed excellent thermal conductivity, and a certain degree of recoverability under cyclic compressive loading.•The sample with s...
