Abstract
An epoxy resin composition is provided which includes a polycrystalline structure comprised of a plurality of monocrystalline structures. The plurality of monocrystalline structures are respectively comprised of a plurality of silicon oxide colloidal particles regularly aligned in epoxy resin. The plurality of silicon oxide colloidal particles are not contacted with each other. The mean distance between the silicon oxide colloidal particles adjacent to each other is less than 330 nm. The mean particle size of the plurality of silicon oxide colloidal particles is less than 290 nm. The concentration of the plurality of silicon oxide colloidal particles is 10-50% by mass. A relative permittivity of 4 or more is ensured. A method for producing the epoxy resin composition is provided. Building materials, ornaments and optical materials, each using the epoxy resin composition, are also provided.
