graphitized carbon 

https://doi.org/10.1351/goldbook.G02693
A graphitic carbon with more or less perfect three-dimensional hexagonal crystalline order prepared from non-graphitic carbon by graphitization heat treatment.
Note: Non-graphitizable carbons do not transform into graphitic carbon on heat treatment at temperatures above 2500 K and therefore are not graphitized carbons.
