Zircar's unique process for manufacturing yttria-stabilized zirconia cloths and felts is also used in the production of pure zirconia refractory fibers and textiles without stabilizers. For those processes which are intolerant of yttria, these unstabilized pure zirconia fiber products provide much of the same high performance insulating benefits. Pure zirconia fibers exist in the monoclinic crystal phase and appear white in color. Our high purity zirconia fiber and textiles are offered in six different standard product forms; bulk fiber Type ZOBF, two felts Types ZOF-50 and ZOF-100 and three types of knit cloth Types ZOK-15, ZOW-15 and ZOW-30.
APPLICATION INFORMATION
Pure zirconia cloth is used as high temperature insulation for advanced energy systems.
