Method of producing composite oxide ceramics |
摘要 |
The present invention provides a method of producing composite oxide ceramics which is capable of efficiently producing single-phase multi-component metal oxide ceramics having less impurity phase and excellent dielectric characteristics, by a simple process comprising sintering at a low temperature. The method has the steps of mixing a metallic hydroxide or hydrous gel with a plurality of metallic oxide powders to prepare a raw material mixture powder, activating the raw material mixture powder by mechanochemical treatment for grinding the raw material mixture powder with a degree of impact, which provides a centrifugal effect of 15 or more, to form a precursor, and synthesizing composite oxide ceramics by heat treatment of the activated raw material mixture powder (precursor).
