抄録

To elucidate the chemical mechanical polishing (CMP) performance of perovskite oxide abrasive grain for glass, we investigated electronic states of CaZrO3 and SrFeO3 by the first-principles calculation. The calculation results show that the Zr and Fe atoms in CaZrO3 and SrFeO3 take low valence states. We suggest that the metal atoms in perovskite oxide are effective for the glass polishing since low-valent metal atoms can weaken the Si-O bond of the glass surface by electron donation based on our reported CMP mechanism of glass by CeO2 abrasive grains.
