<P>PROBLEM TO BE SOLVED: To provide a process which is simplified and is decreased in the generation of inferior goods of a compound oxide. <P>SOLUTION: The process of manufacturing the compound oxide includes: a raw material preparing process in which a first compound of at least one of a compound which contains a first element and carries out hydration when coexisting with water and a compound after hydration containing the first element, and a second compound including a second element are mixed making water as a solvent to obtain a mixed raw material; a molding process which molds a mixed raw material to obtain a molded body; and a calcinating process which warms the molded body at a temperature raising rate below a range of a predetermined slowly raising rate to calcinate and to obtain a calcinated body. When the first element is magnesium and the second element is aluminum, 30°C/h or less (up to 600°C) and 100°C/h or less (600-1,500°C) are desirable. <P>COPYRIGHT: (C)2010,JPO&INPIT |
