Thermodynamic assessment of the Al2O3–ZrO2, CaO–Al2O3–ZrO2, and Al2O3–SiO2–ZrO2 systems
Ceramics International, 2022Abstract All available thermodynamic data and phase diagram data in the Al2O3–ZrO2, CaO–Al2O3–ZrO2, and Al2O3–SiO2–ZrO2 systems at 1 bar total pressure were critically evaluated and assessed simultaneously to obtain a set of the optimized Gibbs energies of all phases in the systems.

Dechlorination of chlorobenzene in subcritical water with Fe/ZrO2, Ni/ZrO2 and Cu/ZrO2
Journal of Environmental Monitoring, 2009To obtain information about dechlorination of organochlorine compounds in subcritical water catalyzed by metals assisted with ZrO(2), dechlorination of chlorobenzene has been investigated in the presence of Fe/ZrO(2), Ni/ZrO(2) and Cu/ZrO(2) catalysts. The dechlorination efficiency was increased with increasing residence time, temperature and pressure.

Decomposition of Nitrous Oxide on CoOX/ZrO2, CuOX/ZrO2 and FeOX/ZrO2 Catalysts
Reaction Kinetics and Catalysis Letters, 2001On CoOx/ZrO2, CuOx/ZrO2 and FeOx/ZrO2 catalysts, below the limits shown by characterization to have high metal dispersion, the turnover frequency for N2O decomposition is nearly independent of metal content.

Microstructure control for sputter-deposited ZrO2, ZrO2·CaO and ZrO2·Y2O3
Thin Solid Films, 1982Abstract The microstructure of pure and oxide-stabilized cubic ZrO 2 has been determined as a function of the principal deposition conditions for coatings prepared by r.f. diode reactive sputtering. Broad control of crystal structure, phase composition, grain size and crystallographic orientation is obtained by appropriate selection of the target ...
