The effect of dopant species on the sintering resistance zirconia-based ceramics remains a huge challenge in terms both experiment and theory. As one most popular materials for high-temperature protective coatings, it is still urgent to obtain rare earth-doped ZrO2 with high good phase stability. Here, stability earth oxides (La2O3, Nd2O3, Gd2O3, Y2O3)-stabilized zirconia (ZrO2) were thoroughly...

Abstract In this work, the target of zirconia with 2-inch diameter is prepared from powder form having a particle size 5 µm by giving 4 tonnes pressure in hydraulic press. The sintered at 1000-degree Celsius for 10 hrs. Yttria-stabilized also obtained similar process. structural properties both targets are investigated using ?-2? geometry X-ray diffractometer system. changes structure studied d...

Objective: To evaluate the effect of different metal primers and surface treatment methods on the bond strength of 2 resin cements to yttrium-stabilized tetragonal zirconia (Y-TZP) ceramic material. Methods: 240 cylindrical dentin specimens were cut from extracted human third molars. The same number of zirconia ceramic (Cercon) plates were made and assigned to 24 groups based on combinations of...

Four aluminas were used as supports for impregnation with a zirconium oxide with the aim to achieve a coating, without phase separation, between support and modifier. The supports were impregnated with different concentrations of zirconium aqueous resin, obtained through the polymeric precursor method. After impregnation the samples were calcined and then characterized by XRD, which led to iden...

Long-term, reliable operation of Solid Oxide fuel and electrolysis Cell (SOCs) necessitates cells with high strength resistance to mechanical degradation. In this work, strength, Young’s modulus Low-Temperature Degradation (LTD) several zirconia-based SOCs supports are studied. The study shows that replacing 3YSZ a tetragonal zirconia compound having lower stabilizer contents can improve the po...
