The martensitic phase transformation property of ZrO2 enhances the fracture toughness and flexural strength of ceramic materials, imparting them with excellent mechanical properties. Additionally, zirconia's low thermal conductivity and excellent thermal shock resistance can alleviate the brittleness issue of ceramic materials. In summary, toughening primarily utilizes the martensitic phase transformation of ZrO2, which absorbs the energy generated during the transition from the tetragonal structure to the monoclinic structure, inhibiting crack propagation and extension.

Based on this mechanism, the introduction of zirconia into Al2O3 ceramic results in zirconia-toughened alumina (ZTA) ceramics. ZrO2 exhibits phase transformation toughening and microcrack toughening effects in Al2O3 ceramics, strengthening and toughening the material. As a result, ZTA ceramics are considered one of the most promising materials in structural ceramics.

Additionally, due to the high hardness and wear resistance of superhard abrasive particles, most ceramic binders for superhard abrasives are used at relatively high rotational speeds. Therefore, to ensure that abrasive particles can fully exert their grinding performance, ceramic binders for superhard abrasives must possess high strength.

By utilizing the B2O3-Al2O3-SiO2 system as the base ceramic binder and adding varying amounts of nano-ZrO2 as an additive, researchers have studied the effect of its content on the structure and properties of ceramic binders. The results indicate that with the increasing content of nano-ZrO2, the overall performance reaches its peak when the content is 8%, exhibiting a flexural strength of 63.41 MPa and a Rockwell hardness of 129.8 HRC.
