  • Direct reduction experiments of pure iron oxide has been investigated using hydrogen as reducing gas in high temperature tube furnace. The results show that with adding reaction time, iron oxide reductive ratio increases accordingly. The reduction ratio of iron oxide and conductivity of reductive product are different accordingly with different reduction temperatures. After hydrogen reduction at the temperature from 600 ℃ to 900 ℃, reduction ratio of reduction product, reaching above 95 %, increases with the increasing of temperature. The curve of reduction product conductivity changing with time and reduction degree is obtained by testing reduction product's conductivity adopting ac impedance method. The conductivity of product varies accordingly to the different reduction temperature and time. The variation of conductivity indirectly reflects that products with different conductivity have been produced.
