Carbon Pellets from Goodfellow are a unique form of graphite with high purity and precisely controlled properties. With a density of 1.7-2.1 g/cm3, carbon pellets combine low weight with high strength. Their electrical conductivity is similar to other forms of graphite. Carbon pellets have uses across science and industry. For research, they can serve as an inert, stable electrode material. In manufacturing, carbon pellets are molded into complex parts and shapes. As part of Goodfellow's extensive range of carbon and graphite products, these carbon pellets deliver advanced performance.
