Abstract:
(EN) The present invention provides a means for producing an aluminum hydroxide-coated SiC particle powder having an aluminum hydroxide-containing coating layer on the surface of SiC particles. The present invention relates to a method for producing an aluminum hydroxide-coated SiC particle powder, the method having a coating step in which a dispersion containing SiC particles, sodium aluminate and water is maintained at a pH within the range 9-12, and coated particles are formed in which an aluminum hydroxide-containing coating layer is present on the surface of the SiC particles.
(FR) La présente invention concerne un moyen de production d'une poudre de particules de SiC enrobées d'hydroxyde d'aluminium, une couche d'enrobage contenant de l'hydroxyde d'aluminium étant formée sur la surface des particules de SiC. La présente invention concerne également un procédé de production d'une poudre de particules de SiC enrobées d'hydroxyde d'aluminium, le procédé comprenant une étape d'enrobage dans laquelle une dispersion contenant des particules de SiC, de l'aluminate de sodium et de l'eau est maintenue à un pH dans la plage de 9 à 12, et des particules enrobées sont formées, une couche d'enrobage contenant de l'hydroxyde d'aluminium étant présente sur la surface des particules de SiC.
(JA) 本発明によれば、SiC粒子の表面に水酸化アルミニウムを含む被覆層を有する水酸化アルミニウム被覆SiC粒子粉体を製造する手段が提供される。本発明は、SiC粒子、アルミン酸ナトリウムおよび水を含む分散体のpHを9~12の範囲に維持し、SiC粒子の表面に水酸化アルミニウムを含む被覆層を有する被覆粒子を形成する被覆工程を有する、水酸化アルミニウム被覆SiC粒子粉体の製造方法に関する。
