High Temperature Microwave Dielectric Properties of Ceramic Nano and Micropowders
The problem of microwave enhanced mass transport in solids remains an area of great interest and continued research in the microwave processing of materials. Many researchers have reported that microwave sintering of materials reduces the time and often the temperature of the sintering procedure [1]. The mechanisms of the mass transport enhancement phenomenon by microwaves termed “Microwave Eff...
متن کاملHafnium silicate: a new microwave dielectric ceramic with low thermal expansivity.
A HfSiO4 ceramic was prepared by a conventional solid state synthesis method by sintering at 1600 °C. The morphology of the sintered surface was characterized using scanning electron microscopy and atomic force microscopy and the average surface roughness was about 118 nm. The sintered HfSiO4 ceramic has εr = 7.0, Qu × f = 25 000 and τf = -44 ppm °C(-1) at 10 GHz. It exhibits promising thermal ...
متن کاملNovel ultra-low temperature co-fired microwave dielectric ceramic at 400 degrees and its chemical compatibility with base metal
A novel NaAgMoO4 material with spinel-like structure was synthesized by using the solid state reaction method and the ceramic sample was well densified at an extreme low sintering temperature about 400°C. Rietveld refinement of the crystal structure was performed using FULLPROF program and the cell parameters are a = b = c = 9.22039 Å with a space group F D -3 M (227). High performance microwav...
متن کاملHalf-metallic properties of KP compound in a bulk and (001) surface of rock-salt structure: A b-initio study
Given the many applications of half-metals in the spintronics devices, we investigated the half-metallic properties of the KP compound in rock-salt (RS) and cesium chloride (CsCl) structural phases by using density functional theory. The results indicated that the KP compound as the half-metal in the RS structure, in contrast to the CsCl structure, due to the small lattice constant and failure ...
متن کاملMaximum probability domains in crystals: the rock-salt structure.
The present paper studies MX crystals in rock-salt structure (M: Li, Na, K; X: F, Cl, Br, I). They are often described as being formed by ions. Pictures based on quantum mechanical calculations sustain and quantify it. The tools used are (i) the Quantum Theory of Atoms in Molecules, (ii) the Electron Localization Function, and (iii) the maximization of the probability to find in a spatial domai...
