Electrical conductivity of an insulator matrix (alumina) and conductor particle (molybdenum) composites

Different concentrations of molybdenum (from 5 to 35 vol.%) were added to alumina matrices and the resulting mixture hot-pressed to produce dense metal toughened-ceramic composites. Their resulting electrical properties were measured using two-probe impedance spectroscopy, in the range 25–1000 °C. E...
