Title:
ナノ粒子状ランタノイド/ホウ素-化合物又はナノ粒子状ランタノイド/ホウ素-化合物を含有する固体混合物の製造方法
Document Type and Number:
Japanese Patent JP5274249
Kind Code:
B2
Abstract:
The present invention relates to a process for preparing essentially isometric nanoparticulate lanthanide-boron compounds or solid mixtures comprising essentially isometric nanoparticulate lanthanide-boron compounds, which comprises a) mixing i) one or more lanthanide compounds selected from the group consisting of lanthanide hydroxides, lanthanide hydrides, lanthanide chalcogenides, lanthanide halides, lanthanide borates and mixed compounds of the lanthanide compounds mentioned, ii) one or more compounds selected from the group consisting of crystalline boron, amorphous boron, boron carbides, boron hydrides and boron halides and iii) if appropriate one or more reducing agents selected from the group consisting of hydrogen, carbon, organic compounds, alkaline earth metals and alkaline earth metal hydrides dispersed in an inlet carrier gas with one another, b) reacting the mixture of the components i), ii) and, if appropriate, iii) in the inert solvent by means of thermal treatment within a reaction zone, c) subjecting the reaction product obtained by means of thermal treatment in step b) to rapid cooling and d) subsequently separating off the reaction product which has been cooled in step c), with the cooling conditions in step c) being selected so that the reaction product consists of essentially isometric nanoparticulate lanthanide-boron compounds or comprises essentially isometric nanoparticulate lanthanide-boron compounds.
