英文摘要	The sub-micron size diamond powders are ideal abrasives for ultrafine rubbing and polishing. However, the synthesis and preparation of high-quality sub-micron size diamond powders are still faced with lots of difficulties and challenges until now. High-quality diamond powders with sub-micron size were synthesized successfully from naphthalene at a temperature of 1 700 and a pressure of 11 GPa without using metal-catalysts. The phase purity of the synthesized diamond powders was extremely high. Most of the diamond grains were euhedral crystals showed well-developed crystal morphology and dispersed to each other. The frequency distribution of the diamond grain size was in positive skew distribution, values of the mean, median and mode were 158.1, 221.5, 262.5 nm, respectively. For lognormal distribution, the expected value of the diamond grain size and the standard deviation were (243.34.2) nm and (122.35.4) nm, respectively. Nearly 96% of the diamond grains were distributed in the sub-micron size range. It may provide an effective way for the synthesis and preparation of high-quality sub-micron size diamond powders. 2019, Science Press. All right reserved.
