Titanium oxide particles, resin composition for electronic materials, molded article, component for electronic devices, and method for producing titanium oxide particles

Abstract

Titanium oxide particles having a low dielectric loss tangent value are provided. Titanium oxide particles contain titanium dioxide, and the titanium dioxide has an average crystallite size of greater than or equal to 220 nm as determined by a peak at 2θ=27.5°±1.0° obtained in an X-ray diffraction measurement. A method for producing the titanium oxide particles includes a mixing step and a firing step. The mixing step is a step of mixing a titanium compound with a molybdenum compound and at least one of a potassium compound or a sodium compound to form a mixture. The firing step is a step of firing the mixture. A molar ratio of Mo to M1 of the mixture is more than 0.5, where M1 represents Na and K.
