Zircar Zirconia ZYF-A2.13 Zirconia Felt Insulation

Zirconia Felt is a true ceramic textile formed by the unique ZIRCAR process for replicating organic structures in inorganic materials. The zirconia felt structure is a ‘needled felt’ which retains its fibrous nature to 2480°C. The stabilized zirconia composition permits the advantages of fibrous insulations to be extended into temperature regions well above the melting temperatures of siliceous and alumina insulation materials.Zirconia Felt Type ZYF-A2.13 is ZYF-150 in which the zirconia fibers have been surface treated with colloidal alumina, refired, and face milled to provide a very uniform thickness. This post processing results in a stiff sheet.Features: Low Thermal ConductivityHigh PorosityHigh PurityExtreme High Temperature StabilityFibers Stabilized with ~10 wt% YttriaCustom Fillers and Coatings AvailableCan be Cemented with Zircar Zirconia Cement Type ZR-CEMCan be Rigidized with Zircar Zirconia Rigidizer Type ZIR-RIGEasily Cut to SizeAvailable “Off the Shelf”Application Information: This thicker, rigidized felt was developed for use as a diffusion burner membrane for fuel fired heaters installed in long-haul trucks and high end passenger cars. In this application the liquid fuel, gasoline or diesel, is pumped onto one surface of a disk of felt. The fuel then wicks through to the opposite surface which is located in a combustion chamber and evaporates. The evaporated fuel is mixed with air and ignited providing an ‘instant-on’ heat in the vehicle which is independent of the engine heat.ZYF-A2.13 is also used as a setter plate for vacuum sintering flat sheets of powdered metal materials. The felt remains flat during sintering because of its rigid structure.Information provided by Zircar Zirconia.
