INORGANIC OXIDE POWDER, RESIN COMPOSITION, AND COMPRESSION MOLDED ARTICLE

WIPO Patent Application WO/2022/202583

A1

[Problem] To provide: an inorganic oxide powder that makes it possible to provide a resin composition in which the ratio between viscosity during low shear and viscosity during high shear is low; a resin composition that contains the inorganic oxide powder; and a compression molded article that is obtained by molding the resin composition. [Solution] An inorganic oxide powder wherein: in a particle size frequency distribution based on volume, the value of the ratio (second region cumulative frequency / first region cumulative frequency) of the cumulative frequency in a second region in which particle diameter is within the range of 0.001-20 μm to the cumulative frequency in a first region in which particle diameter is within the range of 0.001-10 μm is 1.2-1.4; the value of the ratio (third region cumulative frequency / first region cumulative frequency) of the cumulative frequency in a third region in which particle diameter is within the range of 0.001-35 μm to the cumulative frequency in the first region in which the particle diameter in within the range of 0.001-10 μm is 1.4-2.2; and the cumulative frequency in the third region is 70-95 vol%.
