Właściwości elektryczne i magnetyczne szkła Fe2O3 – SiO2 – PbO
PublicationSzkło Fe2O3–SiO2–PbO wydaje się być obiecującym materiałem do zastosowań w urządzeniach elektrycznych takich jak rdzenie cewek, czujniki pola magnetycznego oraz mikrotransformatory. Jest to spowodowane korzystnymi właściwościami takimi jak stosunkowo wysoka rezystywność oraz w miarę duża przenikalność magnetyczna. Pierwsza wymieniona cecha skutkuje brakiem strat energii na prądy wirowe. Natomiast druga cecha oznacza potencjalną...

Thermal, electrical, and magnetic properties of Fe2O3–PbO–SiO2 glass prepared by traditional melt-quenching and twin roller fast-cooling methods
PublicationIn this study, Fe–Pb–Si oxide glasses containing between 12.5 and 17.5 mol% Fe2O3 were prepared using two different methods comprising traditional melt-quenching and twin roller fast-cooling techniques. The topography and structure of the materials obtained were characterized by X-ray powder diffraction and scanning electron microscopy. All of the materials were found to be amorphous. The topography of most of the glasses comprised...

Polaron hopping conduction in manganese borosilicate glass
PublicationA study on a novel material - manganese borosilicate glass without alkali metals, was reported. It was found that the obtained samples containing high amount of manganese oxide (60MnO–xSiO2–(40 − x)B2O3, x = 5, 10, 15, 20 and 30 mol%) were amorphous and homogeneous. XPS measurements showed that most of manganese ions are at oxidation level of Mn2 + ions and the mean oxidation level slightly moves toward higher value, with increasing...

Impedance Studies of Phosphate-iron Glasses Containing Niobium and Titanium
PublicationThe ac and dc conductivity in phosphate-iron-niobate glasses with addition of titanium oxide was investigated as a function of temperature and frequency with the use of impedance spectroscopy. The topography and microstructure of glasses were investigated by the means of X-ray diffraction (XRD), scanning electron microscopy (SEM), and confocal microscopy methods. The obtained results show that all samples are amorphous but they...
