Abstract: A hollow nano-particle includes a shell layer containing a block copolymer having a hydrophobic organic chain and a polyamine chain, and silica. A hollow silica nano-particle has a porosity of 20% by volume or more and 70% by volume or less, and a thickness of a shell layer containing silica of 3 nm or more and 100 nm or less. A production method for the hollow nano-particle includes: a step of dropping an aqueous solvent while stirring an organic solvent in which a block copolymer having a hydrophobic organic chain and a polyamine chain is dissolved, to obtain a dispersion liquid of vesicles containing the block copolymer; and a step of adding a silica source to the dispersion liquid of vesicles, carrying out a sol-gel reaction of the silica source using the vesicle as a template, and precipitating silica to obtain the hollow nano-particle.

Abstract: Spinel has conventionally been used as mentioned above in applications, such as gems, catalyst carriers, adsorbents, photocatalysts, optical materials, and heat-resistant insulating materials, and is not expected to be used in an application of an inorganic filler having thermal conductive properties. Accordingly, an object of the present invention is to provide spinel particles having excellent thermal conductive properties. A spinel particle having spinel containing a magnesium atom, an aluminum atom, and an oxygen atom, and molybdenum being existed on the surface of and/or in the inside of the spinel, wherein the crystallite diameter of the spinel at the [311] plane is 100 nm or more.
