Abstract

The boron nitride nanosheets (BNNSs)/silicon nitride (Si₃N₄) composite ceramics were prepared by SPS sintering. BNNSs with few layers and transverse size in micron-scale were prepared by ball-milling and ultrasound-assisted liquid-phase stripping. In this work, it was found that the BNNSs prepared by these two methods could enhance the mechanical properties of silicon nitride ceramics, and of BNNSs/Si₃N₄ composite ceramics exhibit better bending strength when adding the ultrasound-assisted liquid-phase stripping BNNSs. The bending strength and fracture toughness of BNNSs/Si₃N₄ composite ceramics was increased by 36% and 51%, respectively, when 2 wt% BNNSs prepared by ball-milling method were added. The pullout of BNNSs, the bridging of cracks, and the deflection of cracks are the main factors of improving the toughness.
