Abstract
Core-shell type composite oxide fine particles are described in which the core particles are oxide fine particles or composite oxide fine particles that do not contain silicon and/or aluminum as main components, and the surface of the core particles is covered with a shell including a composite oxide that contains silicon and aluminum as main components, the shell containing silicon and aluminum in a weight ratio in terms of oxides, SiO/AlO, in the range of 2.0 to 30.0. A dispersion liquid of the core-shell type composite oxide fine particles exhibits very high stability.
