Abstract
Composite materials prepared from barium boromolybdate glasses (MoO3content of 8, 12, or 16 wt %) and a cermet containing iron silicides were characterized by x-ray diffraction and resistivity measurements as a function of temperature. Increasing the content of the semicrystalline constituent first reduces the resistivity and then increases it to its original level. The minimum resistivity of the materials corresponds to a positive temperature coefficient of resistance. The results are interpreted in terms of the micro- and electric structures of the composites.
