结合场发射扫描电镜和纳米激光粒度仪研究了型号 w0.5金刚石的形貌及其在水溶液中分散稳定性的影响。FE-SEM 表明型号 w0.5的金刚石为粒度在几百纳米，形状不规则的纳米颗粒。激光粒度测试表明随着金刚石浓度从0.01 wt.%增加到0.4 wt.%，纳米金刚石的分散粒径先减小后增大，浓度为0.1 wt.%，分散效果最好，中粒径为232.3nm。随着测试温度的升高，分散的纳米颗粒再次团聚，在15℃和25℃时，测试分散粒径最佳。

Morphology and dispersion stability of w0.5 type diamond in aqueous solution have been reseached by both of field emission scanning electron microscopy (FESEM)and nano laser granulometer.FESEM result shows that the w0.5 type diamond consists of ir-regular shaped nano particles of a few hundred nanometers.Laser particle size test shows when the diamond concentration has been increased from 0.01 wt.% to 0.4 wt.%,the dispersion particle size of the nano diamond decreases first and then increases.The disper-sion effect is the best with a median particle size of 232.3nm when concentration is at 0.1 wt.%.With the testing temperature rises,the dispersed nano particles reunite again. The dispersion particle size is the best at the temperature of 15℃ and 25℃.
