Claims6
A composite particle comprising:
- an alumina particle having a card-house structure which is formed of three or more pieces of plate-like alumina and in which the pieces of plate-like alumina are fixed to each other;
- and
- an inorganic coating part provided on a surface of the plate-like alumina,
- and wherein the average particle size of the alumina particle is 3 μm or more and 1,000 μm or less,
- wherein the alumina particle further comprise at least one of silicon and germanium, and wherein
- a content of silicon with respect to 100% by mass of the alumina particles, which is obtained by XRF analysis, is 0.5% by weight to 4% by weight in terms of silicon dioxide (SiO2);
- and a content of germanium with respect to 100% by weight of the alumina particles is 0.01% by weight to 8% by weight in terms of germanium dioxide (GeO2).
