Effect of Co Doping into Strontium-Ferrite Abrasive on Glass Polishing Characteristics

Abstract

Ceria is an excellent abrasive for glass polishing. Ce3+/Ce4+ redox would play an important role during glass polishing using ceria-based abrasive. We have developed an alternative abrasive because of increasing cost and unstable supply of ceria abrasives. We currently focused on the glass polishing characteristics using Fe-based perovskite oxide (SrFeOx) as a candidate. Fe3+/Fe4+ redox would occur as a result of glass/abrasive interaction. In this study, we studied the effect of Co doping into SrFeOx on the glass polishing characteristics. It was found that the removal rate was improved by doping Co into SrFeOx.
