In comparison with graphitized
carbon material used for production of electrodes of arc steel-melting furnaces (8--10 mOhm-m), SER value of thermoanthracite is one order higher, but it is quite acceptable for producing from it electrodes for arc furnaces used for melting calcium carbide and ore-smelting electric furnaces.
In addition, many studies about catalytic methane decomposition over carbon materials have been completed , and one study  regarding carbon fibres with Ni support showed that the carbon fibres (prepared by decomposition of C[H.sub.4]) and graphitized
carbon fibres (GrCF) had better catalytic activity and stability than activated carbon powder or graphite for CMD.
8 to the experimental results for PEN/CNT nanocomposites, the weight fraction was transformed to the volume fraction, taking the densities of PEN (1.407 g/[cm.sup.3])  and the perfectly graphitized
CNT (2.16 g/[cm.sup.3]) .
Among carbon materials, which are widely used in electrometallurgy, the class of coal graphite and the class of graphitized
materials may be singled out.
The highly graphitized
MWCNT structure with average diameter in the range of 6-20 nm and length >600 nm with fewer defect along with graphene stakes and amorphous carbon is observed.

carbon nanofibers for lithium ion battery anodes," Nanoscale, vol.
CNT showed a specific capacity of 640 mAh [g.sup.-1] during the first charge and after 20 charge/discharge cycles the charge capacity of the slightly graphitized
samples degraded to 65.3%, whereas well-graphitized carbon nanotubes showed a specific capacity of 282 mAh [g.sup.-1] during the first charge and 91.5% of their original charge capacities after 20 charge/discharge cycles.
Next, the as-grown carbon microspheres were subsequently graphitized
in a tubular quartz furnace in flowing Ar (30 mL [min.sup.-1]) at atmospheric pressure.
