Material Notes:
Type ZYFB Boards, Discs and Cylinders are rigid, refractory structures composed of yttria-stabilized zirconia fibers that do not undergo the usual phase transitions associated with pure zirconia. Type ZYFB is ideally suited for thermal insulation applications under conditions of ultra-high temperatures and in a variety of severe environments. ZYFB is fired at a high temperature to impart good dimensional stability up to 1650°C and can be used at higher temperatures where some additional sintering can be tolerated. It has good hot strength up to 1400°C and can be used as a self supporting setter for loads equal to twice its own weight up to this temperature.ZYFB is available in two densities. ZYFB-3 has a bulk density of 30 pcf and possesses extremely low thermal conductivity. ZYFB-6 has a bulk density of 60 pcf and is stronger than ZYFB-3. Both are zirconia bonded and have exceptional resistance to oxidizing and reducing atmospheres at high temperatures. Zirconia does, however, lose a small amount of oxygen at very high temperatures in vacuum and inert or reducing atmospheres. This reaction results in a color change from white to gray while most other properties remain essentially unchanged and insulation effectiveness is not impaired.ZYFB has exceptional resistance to most corrosive environments. It undergoes little attack by molten alkali metal chlorides and carbonates at temperatures up to 700°C and withstands aqueous solutions of alkali metal hydroxides at temperatures as high as 230°C. ZYFB will also tolerate exposure to inorganic acids at their boiling point for short lengths of time.Features: Rigid and MachinableHigh Purity Zirconia BondedTwo Densities Available 30 pcf & 60 pcfExtreme High Temperature StabilityFibers Stabilized with ~10 wt% YttriaLow Thermal ConductivityCan be Cemented with Zircar Zirconia Cement Type ZR-CEMCan be Surface Hardened with Zircar Zirconia Rigidizer Type ZR-RIGPre-fired and Organic FreeInformation provided by Zircar Zirconia.
