コア−シェル構造を有する鉄−ケイ素酸化物粒子
Document Type and Number:
Japanese Patent JP5553840
Kind Code:
B2
Abstract:
Iron-silicon oxide particles with a core-shell structure, which have a) a BET-surface area of 10 to 80 m2/g, b) a thickness of the shell of 2 to 30 nm and c) a content of iron oxide of 60 to 90% by weight, of silicon dioxide of 10 to 40% by weight, based in each case on the enveloped particles, where d) the proportion of iron, silicon and oxygen is at least 99% by weight, based on the enveloped particles, and where e) the core is crystalline and the iron oxides comprise haematite, magnetite and maghemite, f) the shell consists of amorphous silicon dioxide and g) at least one compound or a plurality of compounds consisting of the elements silicon, iron and oxygen is/are present between shell and core.
