Abstract:
A process for making a zirconium/metal based fibre, said process comprising:i) mixing a metal salt solution or metal oxide colloidal dispersion, wherein said metal is selected from the group consisting of at least one of a Group IIA metal, a transition metal, a Group IIIA metal and a Group IIIB metal, with a colloidal dispersion of an amorphous zirconium polymer of the formula: [Zr4(OH)12(X)2(H2O)4]n(X)2n.2nH2Oâ€ƒâ€ƒ(I) wherein X is a zirconium polymer compatible anion and n is a whole number from 1 to less than 200, to provide a mixed colloidal dispersion; andforming the mixed colloidal dispersion into the zirconium/metal based fibre.
