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.620 K), 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.
