Carbon and Graphite

In today's fast-paced world of manufacturing, the need for high-quality materials that can withstand extreme conditions, such as carbon and graphite, is becoming increasingly important. Graphite is an allotrope of carbon and thus shares characteristics with it. Both carbon and graphite have become essential in many industries, including aerospace, automotive, and electronics. While both materials are made up of carbon, they have different properties that make them suitable for different applications. The graphene structure of graphite, in particular, gives this material qualities that are sought out by many industries. How Carbon Becomes Graphite Carbon is typically depicted as an irregular,...
