Microwave sintering of alumina has been carried out using SiC and Y‐ ZrO 2 based susceptors. The microstructure the sintered samples rigorously compared correlated to heating behaviour susceptor used. It was found that nature highly influences alumina. results show at high temperatures, electrical conductivity tends screen incident electric field, thus resulting in a surface sample material. When susceptor, analysis reveals volumetric heating, which is signature microwave dielectric loss...
The ultra fast synthesis of nanocrystalline Mg2Si was carried out using microwave radiation. elemental precursors were first milled together under dry conditions to get fine particles. resulting mixture powders Mg and Si cold pressed before being heated by irradiation. Precursors products analyzed X-ray diffraction scanning electron microscopy. high energy ball milling parameters utilized prepare the reactive have quite an influence on behavior Moreover, SEM imaging demonstrates that power...
The effects of MgO doping and specific surface area powder on microwave sintering behavior α‐ Al 2 O 3 were investigated. A comparative study was simultaneously achieved in conventional heating with an identical thermal process. experimental results show that both particle size have significant influence enhancement the densification alumina samples. It is found amount surrounding solubility limit or leading to second phase precipitation MgAl 4 spinel induces more enhancement. gain also...
Abstract Better understanding of the effect multimode‐microwave sintering zirconia‐toughened alumina ( ZTA ) was investigated. A comparative dilatometric analysis conducted between conventional and microwave heating processes, to clarify influence zirconia on densification under electromagnetic field. The thermal gradient sample measurements indicates change volumetric is improved by which adsorbs energy better, thus acting as a susceptor. most beneficial microstructure, toughness, hardness...
We have studied YMnO$_{3}$ by high-temperature synchrotron X-ray powder diffraction, and carried out differential thermal analysis dilatometry on a single crystal sample. These experiments show two phase transitions at about 1100K 1350K, respectively. This demonstrates the existence of an intermediate between room temperature ferroelectric high centrosymmetric phase. study identifies for first time different in YMnO$_{3}$.
