The Influence of Al2O3 Addition on Electrical Properties of Sintered Copper
Electric conductivity is often a very significant property in the application of metals. Electrical properties of metals can be explained from the viewpoint of a quantitative analysis of electronic effects in these materials. The valent electron for copper, whose electronic configuration is 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s is 4s, so it can be assumed that one valent electron is free in each copper atom. Thus, the concentration of conductive electrons is equal to the number of atoms per volume unit2.
