On the Dielectric Constant of Zirconia and Lime-zirconia
Zeitschrift für Naturforschung A, 1971 Abstract The dielectric constant of monoclinic zirconia and of lime-zirconia (up to a CaO content of 20% mole) has been measured at 25 °C by the powder method. For pure ZrO2 the D.C. is 13.5, while for lime-zirconia a non linear dependence on the CaO content has been observed in the measured range, with a maximum at about 14% mole CaO ...

Reusable Nanocatalyst: Zirconia and Sulfated Zirconia
International Letters of Chemistry, Physics and Astronomy, 2014 1,5-benzodiazepines have been synthesized by Nano Zirconia and Nano Sulfated Zirconia in solvent free conditions. Synthesis was carried out by conventional as well as microwave method. Benzodiazepines were synthesized by reacting o-phenylenediamine and few ketones in the presence of catalytic amount of Nanoparticles.
