Applied Electrochemistry and Metallurgy - A Practical Treatise on Commercial Chemistry, the Electrical Furnace, the Manufacture of Ozone and Nitrogen by High-Tension Discharges, and the Metallurgy of Iron, Steel, and Miscellaneous Metals #263283

All materials may be divided, first, into two classes, depending upon whether or not they conduct electrical current. If they con duct, they are called conductors and if they do not, they are designated as insulators. In turn, materials which conduct may again be subdivided into two more classes commonly designated: metallic conductors, or conductors of the first class; and electrolytic conductors, or conductors of the second class. It is important that as a basis for the study of electrolysis a clear idea be acquired as to the distinctive differences between metallic and electrolytic conductors.
