| Abstract |
| Petroleum coke calcined at 1000°, 1300° and l600°C,
petroleum coke based dense carbon aggregate developed at
NML, two varieties of anthracite coke and two varieties of
natural graphite have been studied. Studies on proximate
analyses, specific gravity, crushability index, susceptibility
to oxidation, X-ray diffraction have been made to have a
comparative idea on the properties of the raw materials in
their selection. Anthracite coke is found to have inferior
properties as compared with dense carbon aggregate and
petroleum coke calcines in the case of specific gravity,
electrical resistivity and average crystallite size, etc. and
a little superior property in the case of susceptibility to
oxidation. For structural uses, i.e. furnace blocks, as well
as for continuous type soderberg anode, dense carbon
aggregate may be found quite suitable. |
