Product Information

Zircar Felt Type ZYF is an excellent all-purpose high temperature insulation that can be used as a separator, wrapper, fixture, gasket, cushion, pillow, pad, barrier, cover, layering or packing material in high temperature applications. More specific applications for ZYF are in the Czochralski method of crystal growing as iridium and platinum crucible insulation, and precious metal condensate reclamation material. ZYF is a ceramic textile made using the original ZIRCAR Process at our plant in Florida, NY, USA.  ZYF is a flexible, light weight, porous, needled felt comprised of 4 to 6 micron diameter fibers and is nearly 100% zirconia phase stabilized with yttria.  The fibers are mechanically interlocked and retain their flexible nature up to 1350 °C.  ZYF is a general use insulation with insulating properties that excel at extremely high temperatures and in severe environments such as corrosive, oxidizing and reducing atmospheres.

We use the highest purity materials in our products.  The products contain only minimal trace oxides and no organics that off-gas when heated.  Because Zircar zirconia 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 has low adsorption surface area and vapor pressure, making it useful in high vacuum.
