Patent

CA 2415951

The invention relates to a method of preparing a solution containing particles which contain titanium ions wherein one or more hydrolysable titanium- containing compound(s) is stabilised by oxalic acid in a reaction medium. The reaction further relates to the preparation of titania materials (including particulate materials, coating solutions and films) which comprise or include anatase phase titania, and so are suitable in photocatalytic applications. The invention also deals with a method of preparing B-phase titania.

L'invention concerne un procédé de préparation d'une solution contenant des particules renfermant des ions titane, dans lequel un ou plusieurs composés hydrolysables contenant du titane sont stabilisés par de l'acide oxalique dans un milieu réactionnel. L'invention concerne aussi la préparation de matériaux en oxyde de titane (comprenant matériaux particulaires, solutions de revêtement et films) comportant ou incluant de l'oxyde de titane de phase anatase, et qui conviennent ainsi dans des applications photocatalytiques. Elle concerne enfin un procédé de préparation d'oxyde de titane de phase B.
