A graphite rod is a rod-shaped piece of graphite, which is a naturally occurring form of carbon with a metallic luster and a high conductivity for electricity and heat. Graphite rods are often used as a conductive material in high-temperature applications, such as in furnaces and heating elements, due to their high thermal conductivity and ability to withstand high temperatures without breaking down. They are also used as lubricants and in the manufacture of electrodes and other electrical components. The dimensions of a graphite rod, such as a 4x100mm rod, refer to the diameter and length of the rod. Graphite rods are available in a range of sizes and grades, depending on the specific application. Use this highly-conductive pure graphite rods as probes or even to create graphene from.
