Zircar Zirconia ZYW-30A Zirconia Cloth

Subcategory: Oxide, Zirconium; Oxide

Key Words: ZrO2, zirconium oxide

Material Notes:
Zirconia Cloths Type ZYW are flexible textiles composed of yttria stabilized zirconia fibers that offer extreme temperature and chemical resistance in a flexible form. Type ZYW cloths provide the lowest thermal conductivity of any commercially available refractory material in their class. Type ZYW cloths are true textiles, manufactured using the Zircar process where an organic cloth is converted into an inorganic replica. The fabrics are constructed of continuous individual filaments mechanically interlocked in a woven structure.

ZYW ceramic textiles are ideal for temperatures up to 2200°C and are suitable for applications such as high energy battery separators, thermal insulation in crystal growing furnaces, and hot gas filtration. The fine capillary and pore structure of ZYW, in combination with the hydrophilic nature of zirconia, impart excellent wetting, solution retention, and wicking characteristics, to these materials. The cloths require neither binders nor supporting wires to maintain their construction and will comply somewhat to both tensile and compressive forces due to the mechanical interlocking of the fibers. Elongation of 4 to 8% before breaking allows ZYW to conform to irregular surfaces. ZYW 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.

Zirconia Cloth Type ZYW is available in two formats; Type ZYW-15 and Type ZYW-30A. Type ZYW-15 is a square weave cloth nominally 0.015” thick composed of yttria-stabilized zirconia fibers. Type ZYW-30A is a satin weave cloth nominally 0.025” thick.
