Title
A Study on the Reduction of Zinc Ferrite with Hydrogen
박평주 Pyung C . Park
Abstract
Synthetic zinc ferrite was reduced with hydrogen by the use of thermal balance, in order to understand the course of the reduction. At the initiation of the reaction, zinc ferrite is reduced to Fe₃O₄ and Zn(g) as following equation at 700-900℃ and under 30∼55×10^(-3)mmHg of hydrogen pressure. 3ZnFe₂O₄+4H₂=2Fe₃O₄+3Zn+4H₂O. Activation energy associated with the reaction was determined to be 17.4㎉/㏖. Zinc ferrite decomposes to Fe₃O₄ and Zn(g) at 700∼950℃ under the pressure of 10^(-4)mmHg. And this decomposition process is considered to be a predominant factor in the reduction of zinc ferrite.
