Optimization of mechanical strength of titania fibers fabricated by direct drawing

Yttria stabilized zirconia microtubes for microfluidics under extreme conditions

“…The tubes obtained exhibit a tensile strength and Young's modulus in range 400-600 MPa and 100-150 GPa, respectively. 39,43 Both of these values are comparable to published data for microstructured YSZ dental ceramics. 44,45 It should be noted also that these mechanical characteristics are rarely measured directly for ceramics as in most of cases it is very complicated to prepare the sample specimens in the shape suitable for measurements.…”

Study of the curing mechanism of metal alkoxide liquid threads for the synthesis of metal oxide fibers or microtubes

“…An increase of the tensile strength up to 600-800 MPa (Table 1), and Young modulus up to 150 GPa, and 60-70 GPa is observed for both heat-treated butoxide derived materials, TiO 2 bers and ZrO 2 microtubes, respectively. 13 These outstanding mechanical characteristics' values allow applications in constructing materials as reinforcing components for composites. In most of those applications the hollow geometry offers more advantage then bers.…”

Application of Y–ZrO2 microtubes as dielectric barrier material in a He atmospheric pressure micro-plasma jet

“…The 8% YSZ microtubes used in the current study were prepared as thoroughly described and characterized in previous publications [30,37,38]. The YSZ microtube was melt-jointed onto a top of a large quartz Pasteur pipette capillary (inner diameter ID = 5.5 mm) which narrowed down to about 100 µm on the one end, similarly as described in [30].…”

“…Y-ZrO 2 or YSZ is a material, where yttria is required to stabilize zirconia at room temperature in the tetragonal/ cubic phase. YSZ has high dielectric constant (32)(33)(34)(35)(36)(37)(38)(39)(40)(41)(42) [31], refractive index (2.15-2.2) [32,33] excellent mechanical properties and fracture toughness, chemical resistance and biocompatibility. Due to those properties, YSZ is a very important engineering material that has found use in various fields ranging from dentistry [34] to metallurgy [35].…”

“…High-temperature ionic conductance of YSZ enables the use as electrolyte in solid oxide fuel cells [36]. In our previous works, a method was proposed for the preparation of high-quality YSZ microtubes with a diameter below 100 µm and wall thickness less than 20 µm [30,37,38]. The tubes were composed of structurally homogeneous 100% cubic phase 8% yttria-stabilized zirconia.…”
