| Abstract: | The inert anode of NiFe_2O_4 spinel is of semi-conductor materials, but it couldn't meet the need of inert anode for aluminum electrolysis. In order to improve the electrical conductivity of spinel, TiO_2 was added into NiFe_2O_4 spinel samples. The results of experiments proved that after adding TiO_2, the conductivity of NiFe_2O_4 samples was improved largely. |
