摘要
利用CuWO4+0 .95 8WO3 前驱体还原方法制备Cu -W复合粉。试验结果表明 ,共还原法制备的Cu/W复合粉两相分布均匀 ,还原温度是影响复合粉体的关键因素。 70 0℃还原时 ,不能形成W包覆Cu相结构 ,80 0℃还原时 。
CuWO 4+0.958WO 3 precursor was prepared, and through which,tungsten-copper composites powder was produced. The results indicated that coreduction temperature was intensely affect the appearance of tungsten copper composites powder. Copper was not coated by the tungsten reduced at 700 ℃,instead, partially coated by tungsten at 800 ℃.
