Material Notes:
Type ZYZ Boards and Discs are rigid, refractory structures composed of yttria-stabilized zirconia fibers that are bonded with silica. This unique composition provides Type ZYZ insulation with the low thermal conductivity of zirconia fibers combined with the strength and machinability of a silica bonded material. ZYZ is evenly bonded, allowing it to be machined to tight tolerances and intricate shapes. ZYZ has a lower coefficient of thermal expansion than our Type ZYFB materials. Type ZYZ is ideally suited for thermal insulation and protection applications under conditions of ultra-high temperatures and in a variety of severe environments. ZYZ is fired at a high temperature to impart good dimensional stability up to 1650°C. ZYZ 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. ZYZ produces no smoke or odor and undergoes no physically disruptive phase transitions when heated. ZYZ is available in two forms. ZYZ-3 has a bulk density of 30 pcf and possesses extremely low thermal conductivity. ZYZ-6 has a bulk density of 60 pcf and is stronger than ZYZ-3. Zirconia loses 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.Features: Rigid and MachinableSilica Bond for Thermal Shock ResistanceAvailable in Two Densities; 30 & 60 pcfExtreme High Temperature StabilityFibers Stabilized with ~10 wt% YttriaLow Thermal ConductivityCan be Cemented with Zircar Zirconia Cement Type ZR-CECan be Surface Hardened with Zircar Zirconia Rigidizer Type ZR-RIGPre-fired and Organic FreeInformation provided by Zircar Zirconia.
