摘要：
A dielectric-forming composition includes ABOx crystal particles 100 nm or less in mean particle diameter comprising specific metal species, and an organic solvent, and the composition satisfies at least one of the following conditions:
(i) the concentration of the metal species A in the liquid phase is 1 mol% or less; and
(ii) the water concentration in the composition is 1 wt% or less.
A process for producing ABOx crystal particles 100 nm or less in mean particle diameter comprising specific metal species, the process includes (I) a dissolution step in which a specific organometallic compound having the metal species A and a specific organometallic compound having the metal species B are dissolved in an organic solvent; (II) a hydrolysis step in which water is added to the solution prepared in the dissolution step to perform hydrolysis of a precursor in the solution to form crystal particles; and (III) a purification step in which the crystal particles obtained in the hydrolysis step are purified with an organic solvent.
