Abstract

Abstract

By using titanium dioxide and graphite as raw material,TiO₂/C vacuum carbon thermal reduction experiments were carried out to investigate the effect of carbon ratio on the TiO₂/C vacuum carbothermic reaction process and the reduction product.The experimental results indicates that the reduction process exhibits a characteristic of staged reduction and the extent of reaction at each stage depends on carbon ratio;apparent differences of the reduction products obtained at different carbon ratio lie in free carbon contents and their existing state;with the increase of carbon ratio,particle size of the reduction products decreases and porosity of the product increases;resistivity of the reduction products ranges from 2.61×10^-3 Ω·cm to 4.20×10^-3 Ω·cm with conductivity varying between conductor and semiconductor.
