| 中文摘要: |
| 通过热力学计算分析石英与石墨反应的可行性。研究了机械合金化石英与石墨混合粉末的过程中,球磨工艺(球磨时间、球料比)对机械合金化过程的影响。试验结果表明,采用球料比50∶1,球磨机转速为300r/min,球磨时间为72 h时,体系提供了足够的能量生成碳化硅。 |
| 英文摘要: |
| SiO2and C's react is analysised by theremodynamics count, The influences of ball milling techniques (ball minlling time, ball-to-powder mass ratio)on Mechanical Alloying of SiO2and C mixed powders, in the process the alloying,is invested. The results show that the higher ball milling energy may be obtained when the ball-to-powder mass ratio is 50∶1, and rotation speed is 300 r/min. The solid-state reaction between SiO2and C can be activated to compose SiC, with mechanical alloy in 72 hours. |
