Zircar Zirconia RE Rare Earth Fibers and Textiles

Subcategory: Oxide, Other; Oxide

Material Notes:
The unique process employed by Zircar Zirconia, Inc. to manufacture yttria-stabilized zirconia cloths and felts can also be used to produce rare earth oxide compositions in the same type of textile forms. Oxides of the elements from the Lanthanide series ( atomic# 57, Lanthanum through atomic# 71, Lutetium) can all be made with this process. Mixed rare earth compositions, such as hafnia-ceria, Samaria-ceria and ytterbia-ceria have been made for special applications. The properties and characteristics of the rare earth textiles are similar to the those of the yttria-stabilized zirconia textiles described in product bulletins C-AB, CC, and C-DE. All of these compositions can be produced as bulk fibers in five different ways, as described in Bulletin #C-F. In addition to the five bulk fibers, two thicknesses of felts and three types of cloth, square woven, satin woven, or tricot knit, can be made.
