In the early days of graphite fiber/graphite matrix brake disks on
race cars, the ceramic coating would sometimes crack, allowing oxygen
onto the hot graphite. The result became known in the pits as
"Designer Coal."

Would the coating that protects the graphite from oxidation not

Graphite heat exchangers are now used on domestic condensing hot
