Transparent conducting films of In2O3–ZrO2, SnO2–ZrO2 and ZnO–ZrO2

Thin Solid Films, 2000
The optical transparencies and electrical conductivities of thin films of In 2 O 3 , SnO 2 and ZnO mixed with ZrO 2 have been investigated. These films were deposited on glass substrates at room temperature using pulsed-laser deposition. Indium-zirconium oxide films with a ZrO 2 content up to 15 wt.% were conducting and more than 80% transparent ...

Detailed leakage current analysis of metal–insulator–metal capacitors with ZrO2, ZrO2/SiO2/ZrO2, and ZrO2/Al2O3/ZrO2 as dielectric and TiN electrodes

Journal of Vacuum Science & Technology B, Nanotechnology and Microelectronics: Materials, Processing, Measurement, and Phenomena, 2012
ZrO2-based metal–insulator–metal capacitors are used in various volatile and nonvolatile memory devices as well as for buffer capacitors or radio frequency applications. Thus, process optimization and material tuning by doping is necessary to selectively optimize the electrical performance.

Tribological behaviour of Al2O3/ZrO2-ZrO2 laminated composites

Wear, 2000
Laminated composites were prepared in the system Al2O3-ZrO2. Starting from sheets produced by tape casting a symmetric structure was obtained by superimposing alternated layers of Al2O3/ZrO2 composite and ZrO2. Due to the different thermal expansion coefficients and shrinkage of the two materials the alumina/zirconia external layers of the samples ...

Preparation and characterization of ZrO2 and SO42−-promoted ZrO2

Materials Chemistry and Physics, 1987
Abstract The acid-base and oxidizing properties and the structures of ZrOn prepared with ammonia or urea and ZrO 2 treated with sulfuric acid or ammonium sulfate have been investigated. The treatment of ZrO 2 with so 4 2− caused the remarkable increases in the phase transition temperature to monoclinic form, the surface area and the acid strength

Insights into CO2 methanation mechanism on cubic ZrO2 supported Ni catalyst via a combination of experiments and DFT calculations

, 2021
The CO2 methanation mechanism was studied via combined in-situ FTIR and DFT calculations on the cubic ZrO2 supported Ni catalyst. The formation and evolution of CO2 initial adsorbed species were addressed. The bicarbonates produced from CO2 reacting with

Grafting of ZrO2 powder and ZrO2 membrane by fluoroalkylsilanes

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2004
Abstract The hydrophobic properties of zirconia membrane have been obtained by grafting fluoroalkylsilane on the surface of the ceramic material. Several different grafting experiments were conducted using zirconia powders to determine the optimal conditions of grafting.
