Abstract (en)
[origin: WO2007009577A1] A method for producing coloured nanocorundum is claimed. This method comprises mixing an aqueous solution of aluminium chlorohydrate with crystal nuclei and a precursor of a colouring oxide former or a colouring oxide, after which it is dried, calcined within less than 30 minutes and the agglomerates thus obtained are comminuted.
