Electrical properties of nanostructures in lead-silicate glasses and nanocomposites doped with iron oxide

Description

Electrical properties of iron oxide nanostructures observed in silicate glasses and glass-ceramics were studied. Two different sets of glass samples were prepared. The first group of samples has the composition of (50 − 0.5x)SiO2–(50 − 0.5x)PbO– xFe2O3, where x = 15, 20 and 25 (in mol%). Composition of the second group was 50SiO2–(50−x)PbO–xFe2O3, where x=15 and 20 (in mol%). All samples were prepared by the conventional melt quenching technique; the melting was conducted in air at 1623 K in alumina crucibles. The melts were poured on a brass plate preheated to 573 K and formed into button-shaped samples. Afterwards pellets were annealed at 673K, cooledwith the furnace and polished to the thickness of about 1mm.
Electrical properties were analyzed by electrostatic force microscopy (EFM) NT-MDT Ntegra. Detailed information can be found in: http://dx.doi.org/10.1016/j.ssi.2013.10.008
