  • Patent number: 7531477
    Abstract: A process for making a catalytic rare earth metal oxide-coated microporous particulate material that has the rare earth metal oxide coated on outer surfaces of the microporous particulate material. The process comprises the steps of: i) combining an amount of a colloidal dispersion of rare earth metal oxide hydrate with a compatible microporous particulate material to form a slurry, the microporous particulate material having an average pore size less than the particle size of the colloidal dispersion, to position thereby, the colloidal dispersion on the outer surfaces of the microporous particulate material; and ii) heat treating the slurry to fix the rare earth metal oxide to the outer surfaces of the microporous particulate material.

  • Publication number: 20050009693
    Abstract: A zirconium metal oxide fibre comprises zirconium oxide and a metal oxide. The fibre is made by adding a metal oxide in a suitable form to a colloidal dispersion of an amorphous zirconium polymer. The mixed colloidal dispersion is subsequently made into a fibre. The fibre may be used as a substitute for glass fibre in the manufacture of paper and paper-like materials. The fibre's thickness is substantially uniform and has a length usually in excess of one micron.
