catalytic graphitization

https://doi.org/10.1351/goldbook.C00894
The
transformation
of
non-graphitic carbon
into
graphite
by heat treatment in the presence of certain metals or minerals.
Note:
Catalytic
graphitization
gives a fixed degree of
graphitization
at lower temperature and/or for a shorter heat treatment time than in the absence of the catalytic additives (or a higher degree of
graphitization
at fixed heat treatment conditions). Often it involves
dissolution
of
carbon
and
precipitation
of
graphite
at the
catalyst
particles so that non-graphitizing carbons can be graphitized by this procedure.
