Fourteen kinds of alkali-metal rare earth germanate ceramics, MREGeO 4 (M = Li, Na, K; RE = rare earth), were synthesized and their electrical properties were investigated. The crystal structures of the major phases of MREGeO 4 could be classified into four groups; hexagonal (apatite type...
We have observed some electrical properties of γ-FeOceramics made by oxidizing FeO. The change in electrical resistance during the oxidation from FeOand the transformation to α-FeOare discussed first. The effects of additives and mechanical treatment on the transformation of γ-FeOto α-FeOwere ...
Single-phase spinel manganese cobalt oxides Mn₃-ₓCoₓO₄ dense ceramics were prepared for the first time and their structural/electrical property relationships characterized. The electrical properties, that is, the resistivity at 25°C, the energetic constant, and the resistance drift at 125...
The electrical and optical constants of these ceramics were determined as a function of grain size. The effect of grain size on each measured constant, , was expressed by a simple equation, = A + B/GS . Polarization-reversal properties were also measured and the switching time related with ...

The electrical properties of α-Fe2O3 ceramics depend strongly upon the nature of the precursor and on the sintering conditions. The ceramics obtained from fresh precursors are characterized by the presence of extended defects, which tend to order as the sintering goes on. The p-type conductivity...
The influence of PZN content on the phase structure, microstructure and electrical properties of PZT–PMS–PZN ceramics was studied in order to select the composition of ceramics with excellent dielectric and piezoelectric properties for high power piezoelectric transformers application. In addition, it ...
