Crystallinity, Microstructure and Mechanical Strength of Yttria-Stabilized Tetragonal Zirconia Ceramics for Optical Ferrule

Abstract

Yttria-stabilized zirconia ceramics were prepared by using different raw materials in order to compare commercially available optical ferrule. Injection-molded cylindrical green compacts were sintered in air at 1350°C, 1400°C and 1450°C for 2 hrs, followed by furnace cooling. Crystallinity, microstructure and mechanical strength of the sintered body were evaluated by using an X-ray diffraction analyses, a field emission-scanning electron microscope, a universal tester, and a micro-hardness tester, respectively. For practical usage, the sample B sintered at 1350°C was favorable because of high tetragonality and good mechanical strength

“…As seen, the Cercon, zirconia ceramic sample showed a characteristic X-ray pattern for the high-temperature tetragonal ZrO 2 modification with the highest intensities of the tetragonal (111), (002) and (200) reflections, corresponding to the 2 θ values within the range of 30.0, 34.5 and 35.5°. 33 The Ticer coating was predominantly amorphous. A porous microstructured conversion coating results from components of both the titanium substrate and calcium and phosphorus from the aqueous electrolyte.…”

Yttria stabilized tetragonal zirconia ceramics: preparation, characterization and applicationspplications

“…YSTZ is one of the most promising ceramic materials that are used in structural applications for its high strength and toughness. As it also possesses high oxygen ion conductivity, it can also be used in electrical applications at elevated temperature and also as fiber optic connector like ferrule (Badwal, 1984;Wu and Wu, 1998;Kubo et al, 2000, Kim andHwang, 2011). Several studies about the relationship between microstructure and mechanical properties in YSTZ ceramics have been performed over the past decades (Zhang et al, 2004;Lazar et al, 2008;Ha et al, 2010).…”
