Zircar Zirconia ZYC Zirconia Cylinders

Subcategory: Oxide, Zirconium; Oxide

Key Words: ZrO2, zirconium oxide

Material Notes:
Zircar Zirconia Cylinders Type ZYC are rigid, free standing refractory structures composed of yttria stabilized zirconia fibers that are bonded with silica. The material is evenly bonded, allowing intricate shapes to be machined with tight tolerances. Type ZYC Cylinders possess low thermal conductivity and good resistance to thermal shock and are ideally suited for thermal insulation and protection applications under conditions of ultra-high temperatures and severe environments.

ZYC is dimensionally stable to 1650°C although it can be used at higher temperatures in areas where additional sintering can be tolerated or as back-up insulation. It has good hot strength up to 1400°C. ZYC is resistant to attack by most molten metals and has a high resistance to reaction with other oxide materials.

ZYC Cylinders are phase stabilized with yttria and therefore do not undergo the usual phase transitions associated with zirconia. Electrical conductivity at elevated temperatures is also minimized with low density Zirconia fibers whereas dense Zirconia is an effective conductor at elevated temperatures. ZYC does not couple with radio frequency (RF) radiation used in induction heating, but does couple with microwave energy.

ZYC has no organic binders and will produce no smoke or odor when heated.
