Microwave Synthesis, Characterization, and Photoluminescence Properties of Nanocrystalline Zirconia
We report synthesis of ZrO₂ nanoparticles (NPs) using microwave assisted chemical method at 80°C temperature. Synthesized ZrO₂ NPs were calcinated at 400°C under air atmosphere and characterized using FTIR, XRD, SEM, TEM, BET, and EDS for their formation, structure, morphology, size, and elemental composition. XRD results revealed the formation of mixed phase monoclinic and tetragonal ZrO₂ phas...
متن کاملComputational Study of Thermal Runaway in Microwave Processing of Zirconia
Up to now, reported attempts of multiphysics modeling of high-temperature microwave processing have been limited to fairly idealized models. In this contribution, an original accurate computer model enabling virtual experimentation in microwave processing of zicronia is presented. The model, implementing fully coupled FDTD electromagnetic and thermal algorithms, uses detailed data on temperatur...
متن کاملOn the Mechanism of Microwave Flash Sintering of Ceramics
The results of a study of ultra-rapid (flash) sintering of oxide ceramic materials under microwave heating with high absorbed power per unit volume of material (10-500 W/cm³) are presented. Ceramic samples of various compositions-Al₂O₃; Y₂O₃; MgAl₂O₄; and Yb(LaO)₂O₃-were sintered using a 24 GHz gyrotron system to a density above 0.98-0.99 of the theoretical value in 0.5-5 min without isothermal...
متن کاملCold Pressing, Hydrodistillation and Microwave Dry Distillation of Citrus Essential Oil from Algeria: A Comparative Study
Hydro-Distillation (HD), Cold Pressing (CP) and Microwave Clevenger or microwave Accelerated Distillation (MAD) methods have been compared and evaluated for their efficiency in the extraction of essential oil (EO) from fresh Citrus peels. EO from peel of 4 varieties of Algerian sweet orange (C. sinensis), Lemons (C. limon), Citrons (C. medica), sour orange (C. aurantium), grapefruits (C. paradi...
متن کاملPost-hot isostatic pressing: a healing treatment for process related defects and laboratory grinding damage of dental zirconia?
OBJECTIVE Processing parameters (powder granulation, compaction, debinding, greenbody shaping, sintering) and post-sinter rough, even fine grinding are influencing the final mechanical properties of 3Y-TZP. The hypothesis of this study was that post-sinter hot isostatic pressing (post-HIP) would be beneficial for improving reliability and strength of both sintered and coarse ground sintered zir...
