摘　　要：粉体的粒度和比表面积是影响其性能和应用的关键因素,且粒度和比表面积具有一定的对应关系,通过对不同比表面积的氧化锆和钇稳定氧化锆粉体进行研磨,探讨在不同粒径的条件下其比表面积的变化趋势,发现随着研磨时间的延长,其颗粒粒径越来越小,对应比表面积越来越大,且氧化锆和钇稳定氧化锆粉体呈现相同的趋势。The particle size and specific surface area of the powder are the key factors affecting its performance and application,and there is a certain corresponding relationship between the particle size and specific surface area.Through grinding zirconia powder and yttrium stabilized zirconia powder with different specific surface area,the change trend of specific surface area under the condition of different particle size is discussed.It is found that with the extension of grinding time,the particle size becomes smaller and smaller,the surface area of zirconia is increasing,and zirconia powder and yttrium stabilized zirconia powder present the same trend.
