Abstract

Carbothermal reduction behavior of a saponite/acriflavine complex in various atmospheres was examined and characterized by comparing with that of a saponite/carbon black mixture and raw saponite. There was no substantial difference in the reduction behavior between the complex and mixture when compared at the equal carbon contents (3.4 and 10.4%). It is because of the analogous crystalline state form in both samples before the carbothermal reduction occurs at 1673K. The reduction of carbon-containing samples, regardless of the complex and the mixture, was inhibited under CO atmosphere, and fine oxide spheres were obtained at 1873K.
