We have been exploring experimental conditions to achieve the exfoliation of the layered niobate phase K4Nb6O17
using alkyl amines. In this work, the exfoliation process of the niobate acidic form H2K2Nb6O17 was evaluated in
aqueous solutionmedia using n-butylamine. Different amine/H+
-niobatemolar ratios were used and for each one, two
fractionswere isolated: one that corresponds to the deposited solid (or sediment) and the second one that consists of an
aqueous colloidal dispersion.
