Changed into a form of carbon known as graphite, which is soft and used in pencils and lubricants.
The material was graphitized to improve its conductivity.
Graphitized → It is formed from "graphite" (from Greek "grapho" meaning to write or draw) and the suffix "-ized" (meaning to make or to become). The word "graphitized" means to have been converted into graphite or to have taken on the properties of graphite.
Think of 'writing' or 'drawing' ('grapho') and remember that 'graphitized' means something has been made into graphite.
