A non-graphitic carbon
which cannot be transformed into graphitic carbon
solely by high-temperature treatment up to
under atmospheric pressure or lower pressure.
The term non-graphitizable is limited to the result of heat treatment without additional
influence of foreign matter or neutron
radiation. Non-graphitizable carbon
can be transformed into graphitic carbon
by a high-temperature process via intermediate dissolution
in foreign matter and precipitation
under high pressure or by radiation damage.
