Zircar Zirconia ZYK-15 Zirconia Cloth

Subcategory: Oxide, Zirconium; Oxide

Key Words: ZrO2, zirconium oxide

Material Notes:
Zirconia Cloth Type ZYK-15 is a tricot knit cloth nominally 0.012” thick composed of yttria stabilized zirconia fibers. This material offers extreme temperature and chemical resistance in a flexible form and provides the lowest thermal conductivity of any commercially available refractory fiber material. ZYK-15 cloth is ideal for temperatures up to 2200°C. The melting temperature is 2590°C. It is suitable for applications such as high energy battery separators, thermal insulation in crystal growing furnaces, and for the filtration of hot gases.

ZYK-15 is a true textile constructed of essentially continuous individual filaments fabricated in a tricot knit form. It requires neither binders nor supporting wires in its construction and will comply somewhat to both tensile and compressive forces due to the mechanical interlocking of their fibers. Elongation of 4 to 8% before breaking allows ZYK-15 to conform to irregular surfaces. ZYK-15 can be compressed up to two-thirds of its normal thickness and still recover a major fraction of its original dimension with little fiber damage.

The fine capillary and pore structure of ZYK-15, in combination with the hydrophilic nature of zirconia and the serrated surface of the individual fibers in the knit threads, impart excellent wetting solution retention and wicking characteristics to this material.
