| 摘 要： | 采用非均匀成核法，使硫酸铝在石墨悬浮液中水解，在石墨表面包覆一层Al（OH）3。以角度法测量接触角，用差热失重检测石墨的抗氧化性。通过试验探讨了pH值、硫酸铝浓度等包覆条件对石墨表面改性的影响。结果表明：改性后石墨对水的润湿性和抗氧化性都有所提高。

| Abstract: | Graphite particles were coated with Al(OH)_3 by heterogeneous nucleation process of Al_2(SO_4)_3 in graphite aqueous slurries.Contact angle was measured.Oxidation resistance of treated graphite was measured by TG-DTA analysis.The author studied the effects of preparing conditions such as pH,concentration of aluminum sulphate of graphite on surface modification.The results showed that the water wettability and oxidation resistance of the coated graphite were improved. |

| Keywords: | surface modification preparing conditions coating by aluminum sulphate graphite wettability |
