Electrically conductive AlN ceramics were fabricated by the addition of a small amount of B4C and sintering aid, and hot-press sintering in a nitrogen atmosphere. The electrical resistivity of AlN ceramics decreased remarkably from 1014 cm to the range of 100 to 102 cm by a minimum of 2.3 wt% of B4C addition. This resistivity decrease was caused by forming three-dimensional networks composed ...

Electrical Conductivity of Metals - ThoughtCo
2020-3-2 · Electrical conductivity in metals is a result of the movement of electrically charged particles. The atoms of metal elements are characterized by the presence of valence electrons, which are electrons in the outer shell of an atom that are free to move about. It is these "free electrons" that allow metals to conduct an electric current.
