A carbonaceous material intermediate between a fusible mesophase pitch
and a non-deformable green coke
produced by incomplete carbonization
at temperatures between the onset of fusion (of coal, ca.
), and complete devolatilization. Semicoke still contains volatile matter, therefore.
Semicoke may be conceived as covering a continuous range from coal that has not yet
been fused to coke breeze
. Semicoke can also be used as a filler
in carbon mixtures.
