Eco Friendly Nitration of Toluene using Modified Zirconia

open access: yesBulletin of Chemical Reaction Engineering & Catalysis, 2013
Nitration of toluene has been studied in the liquid phase over a series of modified zirconia catalysts.  Zirconia, zirconia- ceria (Zr0.98Ce0.02)O2, sulfated zirconia and sulfated zirconia- ceria were synthesised by co precipitation method and were ...

Hydrothermal and Solvothermal Synthesis of Cerium-Zirconium Oxides for Catalyst Applications

open access: yesInternational Journal of Technology, 2019
Cerium oxide (CeO2) is a rare earth metal oxide that has high oxygen storage capacity at low temperature. In order to enhance this capacity, as well as its thermal stability, it is necessary to combine CeO2 with zirconium oxide (ZrO2).

Tribology and in-vitro biological characterization of TiO2 addition on ceria stabilized zirconia-toughened alumina (CSZTA) composite

open access: yesJournal of Asian Ceramic Societies, 2023
The effect of TiO2 addition on tribology and in-vitro biological characteristics of ceria-stabilized zirconia-toughened alumina (CSZTA-TiO2) ceramic composites were examined and presented in this study. Through the powder metallurgy route, the TiO2 added

Synthesis of Ceria Zirconia Oxides using Solvothermal Treatment

open access: yesMATEC Web of Conferences, 2018
Ceria oxide (CeO2) is widely used as catalyst with high oxygen storage capacity at low temperature. The addition of zirconia oxide (ZrO2) to CeO2 can enhance oxygen storage capacity as well as thermal stability.

Mechanical properties of partially stabilized zirconia for dental applications

open access: yesJournal of Asian Ceramic Societies, 2019
In esthetic dental care, porcelain-fused-to-metal crowns have long been used for dental restoration. Since a dental prosthesis is placed in the harsh environment of the oral cavity over long periods, metal allergy due to eluate from the metal frame has ...
