ZYF Zirconia Fibre Felts, up to 2,100 °C
ZYF zirconium oxide fibre felts are the result of the Zircar Process by Zircar Zirconia which transforms an organic fibre into a ceramic fibre. The new fibre usually has a diameter of 6 to 10 μm and a serrated outer face. Zirconium oxide fibres are made of nearly 100 % zirconia phase stabilized with 10 % yttria.
ZYF is a flexible, light weight, porous, needled felt. ZYF is an excellent all-purpose high temperature insulation that can be used in methods of crystal growing as iridium and platinum crucible insulation, and precious metal condensate reclamation material. These felts can withstand up to 2,000 °C without losing their properties. They are inorganic and do not require organic binders.
Because zirconium oxide fibers are yttria stabilized, they do not undergo the disruptive phase transition of pure zirconia. ZYF is non-reactive to alkali vapors, salts or strong hot solutions and is not wet by most molten metals. ZYF excels at extremely high temperatures and in severe environments such as corrosive, oxidizing and reducing atmospheres.
Main Applications of Zirconium Oxide Fibre Felts
