Abstract
Provided is a metal oxide production apparatus that implements a flux evaporation method. The production apparatus includes a firing furnace configured to subject a metal compound to firing in the presence of flux, a cooling pipe connected to the firing furnace and configured to convert vaporized flux resulting from the firing into powder, and a recovery means configured to recover powdered flux converted in the cooling pipe. Furthermore, provided is a metal oxide production method comprising a step (1) of subjecting a metal compound to firing in the presence of flux and obtaining a metal oxide and vaporized flux, a step (2) of converting the vaporized flux into powder by cooling the vaporized flux, and a step (3) of recovering powdered flux resulting from the converting.
