摘要：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. © 2020, The Minerals, Metals & Materials Society.
