ZYK-15 – Zirconia Knit Cloth
High Temperature Yttria Stabilized Zirconia Cloth
Thin… Flexible… Foldable… Wrappable… Die Cuttable…
Fibrous ceramic knit is a superior electrochemical separator and insulator that can withstand molten alkali chlorides, molten metals and extreme temperatures in excess of 2000 oC.
Zircar Zirconia Cloth ZYK-15 is a tricot knit cloth nominally 0.012” thick. 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 is made using the original ZIRCAR Process at our plant in Florida, NY, USA, and is comprised of continuous individual filaments fabricated in a tricot knit form that is nearly 100% zirconia phase stabilized with yttria. It is suitable for applications such as high energy battery separators, thermal insulation in crystal growing furnaces, and for the filtration of hot gasses. ZYK-15 has exceptional resistance to molten alkali metal chlorides and carbonates at temperatures as high as 700 oC, to aqueous solutions of alkali metal hydroxides at temperatures as high as 220 oC and to attack by hot caustic solutions, such as KOH.
ZYK-15 is a true textile. 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 fibers. Elongation of 4 to 8% before breaking allows to ZYK-15 to conform to irregular sizes. 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.
