| Abstract: |
| 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. |
