Inorganic nanofibrous powders

NnF CERAM® – Y/La-ZrO2

Product description

Yttria- and lanthanum-doped zirconium dioxide nanofibrous powder is newly incoming special material produced by industrial production technology operated by Pardam, s.r.o. in the Czech Republic. The attractiveness of this material is due to the combination of excellent properties. Doped zirconium dioxide nanofibers offer not only high ionic conductivity, thermal stability, great mechanical properties, but also considerably large specific surface area. This material gives a new dimension to catalysis, fuel cells, advanced ceramics, optical device, electrochemical electrodes etc.
