RESEARCH ON THE PREPARATION OF SUPERFINE IRON POWDER WITH NANO-SIZED FERRIC OXIDE POWDER

The preparation of superfine iron powder by reduction of nano-sized ferric oxide with H_2 at different tempareture for different time was investigated.Results show that nano-sized ferric oxide has high reactivity,lower reduction temperature for superfine iron powder preparation.The reduction rate of ferric oxide powder and specific surface area of superfine iron powder were measured,compared and analyzed.
