In the latter, unstable electrical behaviour was noted above the Tammann temperature in the hematite, but not in the ferric oxide.Additionally, isothermal sintering experiments were carried out, at 975 to 1200° C on red ferric oxide, and at 1350 to 1400° C on black ferric oxide. The ...
ELECTRIC conductivityQUANTUM tunnelingFERRIC oxideGLASSDIELECTRICSA survey of relaxation processes in glasses exhibiting ionic and electronic鈥搃onic conductivity mechanisms is presented.

Here we combine high pressure and temperature electrical conductivity experiments, Raman spectroscopy and first-principles simulations to investigate the state of hydrogen in the pyrite-type FeO2Hx (x ≤ 1), which is a potential H-bearing phase near the core–mantle boundary. We find that ...

Iron Oxide (Fe3O4) nanoparticles were deposited on the surface of low density polyethylene (LDPE) particles by solvothermal method. A magnetic field was introduced to the preparation of Fe3O4/LDPE composites, and the influences of the magnetic field on thermal conductivity and dielectric properties...
The constant \ gr o of the suggested formula can be obtained from electrical measurements. If expressed as K g = K- K e, the lattice conductivity of iron shows an anomalous change at the Curie point, being much larger in the state of spontaneous magnetization than in the paramagnetic state...
