Table of Electrical Resistivity and Conductivity

27/06/2019· This table presents the electrical resistivity and electrical conductivity of several materials. Electrical resistivity, represented by the Greek letter ρ (rho), is a measure of how strongly a material opposes the flow of electric current. The lower the resistivity, the more readily the material permits the flow of electric charge.

Silicon carbide - Wikipedia

06/04/2013· Silicon carbide is a compound of silicon and carbon with the chemical formula SiC. It occurs in the extremely rare mineral moissanite. Silicon carbide grains are bonded together by sintering to form hard ceramics that are used in appliions requiring high endurance. SiO 2 present in plant material can be used to produce silicon carbide with high

Direct reduced iron - Wikipedia

Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) into iron by a reducing gas or elemental carbon produced from natural gas or coal.Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting
