Resistivity of Carbon, Graphite The Physics Factbook

Because of its layered molecular structure, graphite has parallel and perpendicular resistivities, depending on how the graphite is oriented in a circuit There is also highdensity graphite, lowdensity graphite, granulated, coarse, grease, and every other form that affects the resistivityOC Carbon carbon/graphite materials combine the superior strength, hardness, and wear resistance of carbon with the natural lubricity of graphite These chemically bonded carbon materials are strong and thermally stable and are inert in most chemical and corrosive applications When even Carbon/Graphite Grade Selection GuideOver twice as stiff as aluminum, these high modulus carbon fiber tubes resist bending They’re often used in instrumentation and other precision applications that require a rigid, high strength, lightweight materialGraphite and Carbon Fiber Bars and Rods McMasterCarrGRAFOIL flexible graphite is resistant to attack from nearly all organic and inorganic fluids with the exception of highly oxidizing chemicals and concentrated, highly oxidizing mineral acids such as nitric or sulfuric acids GRAFOIL flexible graphite is an extremely chemically resistant materialAppendix 2 Chemical Compatibility of Materials with Carbon Graphite materials are porous as produced and are often impregnated or have a coating applied to impart additional characteristics such as imperviousness, increased strength, and Thermal Conductivity Impregnants include: Resins, Antimony, Copper, Silver, Babbitt, Bronze and other Inorganic materialsCarbon Graphite Material Products St Marys Carbon
