Inorganic nanofibrous powders

NnF CERAM® – ZrO2

Product description

Zirconium dioxide nanofibrous powder is a novel kind of ceramic material produced by industrial production technology operated by Pardam, s.r.o. in the Czech Republic. Nanofibrous products are fully comprised of ceramic basis of zirconium oxide with a minor amount of porous particles from the same material. Zirconium dioxide nanofibrous material is basically produced in monoclinic and tetragonal crystal phase modification, but the production setup can be simply modified to obtain other phases such as tetragonal or cubic zirconia. The properties and characteristics obtained by combinations of nanofibrous morphology and conventional properties of zirconia material predestine ZrO2 nanofibers for applications in many commercial products.
