ALKALINE EARTH METAL COMPOUND FINE PARTICLE DISPERSION AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a magnesium oxide fine particle dispersion capable of producing a magnesium oxide film having a high visible light transmittance by an application method.SOLUTION: There is provided a dispersion in which fine particles of an alkaline earth metal compound selected from the group consisting of an oxide, a hydroxide and a carbonate of an alkaline earth metal are dispersed in a dispersion medium. In the particle size distribution measured by a dynamic light scattering method, the Dis not more than 200 nm and the dispersion liquid does not contain 1% or more of particles having a particle diameter of 500 nm or more.
