Pardam will be presenting its work and products at the conference NANOTECH DUBAI 2013.
28 Oct – 30 Oct 2013 | Dubai – United Arab Emirates
Our scientist Ing. Aneta Krausová will present our new materials: Yttria- and lanthanum-doped zirconium dioxide nanofibers: the efficient way to increase the specific surface area.
The technique of electrospinning and a novel technique of forcespinning were employed to fabricate yttria- and lanthanum-doped zirconium dioxide nanofibers. Solutions containing polyvinylpyrrolidone and suitable precursors of zirconium, yttrium and lanthanum ions were prepared by sol-gel method . Nanofibers of zirconia and doped-zirconia dioxides were obtained by calcination at different elevated temperatures. The BET (Brunauer-Emmett-Teller) specific surface areas of these fibers were measured and compared in this paper. X-ray diffraction was used to determine the crystalline phase of the final product and the fibers were also characterized by means of SEM (scanning electron microscopy). The results confirmed that dopants effectively enhance specific surface area of the zirconium dioxide nanofibers.
