Tetragonal BiFeO3 on yttria-stabilized zirconia

Effect of high-temperature aging on the thermal conductivity of nanocrystalline tetragonal yttria-stabilized zirconia

The thermal conductivity of yttria-stabilized zirconia (YSZ) thermal barrier coatings increases with high-temperature aging. This common observation has been attributed to the densification of the coatings as porosity sinters out and pores and cracks spheroidize to minimize their surface energy. We show that the thermal conductivity of fully-dense 3 mol.% Y2O3 stabilized zirconia (3YSZ) also in...

Initial Bacterial Adhesion on Different Yttria-Stabilized Tetragonal Zirconia Implant Surfaces in Vitro

Bacterial adhesion to implant biomaterials constitutes a virulence factor leading to biofilm formation, infection and treatment failure. The aim of this study was to examine the initial bacterial adhesion on different implant materials in vitro. Four implant biomaterials were incubated with Enterococcus faecalis, Staphylococcus aureus and Candida albicans for 2 h: 3 mol % yttria-stabilized tetr...

Characteristics of yttria stabilized tetragonal zirconia powder used in optical fiber connector ferrule

The tetragonal to monoclinic (t ! m) phase transformation during low temperature ( 100 8C) degradation (LTD) of yttria-stabilized tetragonal zirconia polycrystals (Y-TZP) sintered in air at different temperatures was investigated. It is found that the sintering temperature affected the density, crystalline phase and microstructure of the sintered body, as well as the LTD behavior. Also, the ons...
