✦ Synopsis

An attempt was made to clarify, from the view~int of the behavior of the quinoline soluble component, the reason for the promotion of the sinterabiIity of raw coke powder caused by long grinding. Raw coke powder manufactured at 460°C was ground for 44 hr by an automatic mortar. The ground powder was then treated with quinoline to remove the soluble component. Two powders, as-ground and quinoline-treated.

were compressed into cylindrical compacts 20 mm in dia., and then heat-treated up to 2800°C.

Three points were clarified; (1) the amount of the quinoline soluble component was not increased by grinding; (2) in ground raw coke powder compact, the quinoline soluble component existed as a boundary phase, and transformed into a porous carbon phase by successive heat-treatment; (3) the ground raw coke powder treated with quinoline showed relatively better sintembility at elevated tem~ratures, that is, the quinoline soluble component in ground raw coke hindered the sintering.
