LIQUID DISPERSION OF FINE CORE/SHELL COMPLEX OXIDE PARTICLES, METHOD FOR PRODUCING THE LIQUID DISPERSION, AND COATION COMPOSITION CONTAINING THE FINE PARTICLES |
摘要 |
Core-shell type composite oxide fine particles are disclosed 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 2 /Al 2 O 3 , in the range of 2.0 to 30.0. This weight ratio results in a high surface negative charge and a high rate of the coverage of the core with the shell, whereby a dispersion liquid of the core-shell type composite oxide fine particles which exhibits very high stability is obtained. |
