Crystalline Structure and Dielectric Properties of Li1+x-yNb1-x-3yTix+4yO3 M-Phase Solid Solutions
The structure and dielectric properties of the so-called M-phase solid solutions in the Li2O-Nb2O5-TiO2 system have been investigated. Detailed studies of the lattice parameters of these phases agree well with structure models based on intergrowths of LiNbO3 slabs with a titanium-rich corundum-type layer. The relative permittivity ranges from ~80 to ~55; microwave quality factors increase with ...
متن کاملSynthesis and Dielectric Properties of Li1-x+yTa1-x-3yTix+4yO3 M-Phase Solid Solutions
The synthesis, structure, and dielectric properties of the so-called M-phase solid solutions in the Li2O-Ta2O5TiO2 system were investigated. Although the range of stability of the tantalate phases is more limited compared with their niobate counterparts, they have identical structures based on intergrowths of LiTaO3type blocks separated by corundum type layers. The dielectric constants of the t...
متن کاملDIELECTRIC PROPERTIES OF Li1+x-yNb1-x-3yTix+4yO3 M-PHASE SOLID SOLUTIONS
The structure and dielectric properties of the so-called “M-phase” solid solutions in the Li2O-Nb2O5-TiO2 system have been investigated. Detailed studies of the lattice parameters of these phases agree well with structure models based on intergrowths of LiNbO3 slabs with a Ti-rich corundum-type layer. The relative permittivity ranges from ~80 to ~55; microwave quality factors increase with the ...
متن کاملPhase segregation in cerium-lanthanum solid solutions.
Electron energy-loss spectroscopy (EELS) in combination with scanning transmission electron microscopy (STEM) reveals that the La enrichment at the surface of cerium-lanthanum solid solutions is an averaged effect and that segregation occurs in a mixed oxide phase. This separation occurs within a crystalline particle, where the dopant-rich phase is located at the surface of the dopant-deficient...
متن کاملDielectric and Birefringent Properties of [(CH3)2NH2]5Cd2CuCl11 Solid Solutions in the Region of Their Phase Transitions
On the basis of the optical and dielectric investigations of [(CH3)2NH2]5Cd2CuCl11 solid solutions the existence of phase transitions at T1 = 175 K and T2 = 117.5 K was confirmed. Both phase transitions were found to be shifted toward lower temperatures with respect to the corresponding transitions in the “host” [(CH3)2NH2]5Cd3Cl11 crystals. It was found that the proton conductivity in [(CH3)2N...
