对研磨前后ZrB2粉料的粒径分布、颗粒形貌、等静压坯体密度和料浆粘度的变化作了对比分析，研究结果表明：研磨后ZrB2颗粒的粒径明显减小，约为1．3μm；研磨前ZrB2颗粒多为球形，研磨后棱角明显；等静压坯体密度由研磨前的2．9g／cm^3提高到研磨后的3．3g／cm^3；研磨前的ZrB2粉料料浆的粘度较小。

The pre and post grinding technology, the difference of particle morphology, body density of isostatic pressing and viscosity of the slurry were analyzed. The results show that： ZrB2 particles size was evidently decreased; approximately 1.3 m. ZrB2 particles were spherical before grinding, with edges and corners after grinding. Body density of isostatic pressing was increased from 2.9g/cm^3 to 3.3 g/cm^3 after grinding. The viscosity of the slurry was smaller before grinding
