semicoke

https://doi.org/10.1351/goldbook.S05590
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.
Note:
Semicoke may be conceived as covering a continuous range from coal that has not yet been fused to @C01143@. Semicoke can also be used as a @F02363@ in carbon mixtures.
