- Model CeZrO4 - Cerium/Zirconium Bi-Oxide Composite Nanofibrous Powder



Cerium/Zirconium bi-oxide composite nanofibrous powder is a very interesting kind of ceramic material produced by industrial production technology operated by Pardam, s. r. o. in the Czech Republic. This material is fully comprised of ceramic basis of cerium/zirconium bi-oxide composite nanofibers with minor amount of porous particles of the same material. Cerium/zirconium bi-oxide have attracted great deal of attention because it combines the highly refractive properties of zirconia with the oxygen-storage properties of cerium. The mixed oxides have also better thermal resistance, chemical stability and ionic conductivity and posses a strong resistance to sintering. This material has great potential in catalytic application due to combining catalytic properties with very high specific surface area, but may be used in whole the range of application of simple ceria and zirconia oxide.
