SOLID STATE REDUCTION REACTIONS OF CuO BY Si USING HIGH ENERGY BALL MILLING |
| |
| Abstract: | A composite consisting of Cu and SiO 2 has been prepared with Si and CuO powders by using high energy ball milling. The results indicated that the solid state reduction reactions which may not be realized under usual conditions can be carried out through high energy ball milling. The reduction products were nanometer order Cu and non crystalline SiO 2, depending upon a favourable high energy ball milling condition. Therefore nanometer order oxide metal composites can be prepared directly using high energy ball milling technique. |
