The caking property of coal, the most critical factor in the met-allurgical coke making, is reviewed while the difference between caking and coking properties is clarified and caking coal is defined. Then, the transformation process from coal to coke is explained with respect to the behavior of coal particles during heating and the plastic behavior (350 to 500°C) and the resolidification-contraction behavior (500 to 1000°C) of the slack layer. Further, a description is given to the transformation of petrograhic components of coal into the coke texture (optical ani-sotropic texture) and researches on the dynamics of carbonization.
