Material Notes:
Type FBD Boards, Discs and Cylinders are high strength, uniform, rigid, refractory structures composed of zirconia fibers stabilized with yttria. Type FBD is Zircar Zirconia's strongest and most stable zirconia material. Type FBD is ideally suited for thermal insulation and protection applications under conditions of ultra-high temperatures and in varied atmospheres. FBD has been high fired and is tightly bonded resulting in nearly dust free use. This tight bonding makes machining to tight tolerances possible. FBD is dimensionally stable to 2000°C and can be used at higher temperatures in areas where some sintering can be tolerated. FBD has good hot strength up to 1700°C and can be used as a self supporting setter for loads equal to twice its own weight up to this temperature. It has 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. Although this reaction results in a color change from white to gray, other properties remain essentially unchanged and insulation effectiveness is not impaired. FBD has exceptional resistance to most corrosive environments. It undergoes little attack by molten alkali metal chlorides and carbonates at temperatures as high as 700°C and withstands aqueous solutions of alkali metal hydroxides at temperatures as high as 230°C. FBD will tolerate exposure to inorganic acids at their boiling point for short lengths of time. FBD contains no organic binders, produces no smoke or odor and undergoes no physically disruptive phase transitions when heated.Features: Rigid and MachinableOur Most Dense, Highest Strength, Fibrous Zirconia MaterialHigh Purity Zirconia BondedExtreme High Temperature Stability Fibers 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.
