The conducted research focused on the mechanical (Young’s and shear moduli, flexural strength, hardness, and fracture toughness), thermal (thermal conductivity and coefficient of thermal expansion), and electric (dielectric properties) characterization of MgO-Al2O3, MgO-CaZrO3, and stable YSZ ceramic composites.
15 Νοε 2011 · Increased strength and improved erosion resistance are required for future infrared windows working in harsher mechanical and thermal environments than those used today. In this study, Y 2 O 3 –MgO–ZrO 2 composite nanopowders were synthesized using a sol–gel combustion process.
13 Μαΐ 2021 · We report a remarkably high plasma etching resistance of nanostructure YM surpassing the plasma resistance of commercially used transparent Y2O3 and MgAl2O4 ceramics.
1 Οκτ 2021 · For this purpose, a simple but effective methodology for comparing the transport behavior was proposed in this study, which involves high-temperature interactions between YbYSZ ceramic powders and CMAS melts.
5 Ιαν 2022 · ZrO 2 ceramic exhibits the characteristics of high hardness, good thermochemical stability, desirable biocompatibility, and unique stress-activated tetragonal to monoclinic transformation toughening, thus having broad development prospects.
7 Σεπ 2020 · Ceramics with high phase stability and low thermal conductivity have been produced in the ternary ZrO2–Sc2O3–Gd2O3, ZrO2–CeO2–Gd2O3, ZrO2–YbO1.5–TaO2.5, and ZrO2–Yb2O3–TiO2 systems.
30 Ιουλ 2022 · An easy approach is described for the preparation of ZrO2-coated Y2O3 nanopowder from a solution of zirconium nitrate with commercial Y2O3 nanopowder. The evolution process of the ZrO2 coating layer upon calcination, such as the phase and microstructure of the particles’ surface, was studied.
