โœฆ Synopsis

To monitor changes in the fissure density in the interior of coke, pieces of an industrial metallurgical coke,were examined before and after heat treatment and gasification in carbon dioxide at 1173 K, using an ultrasonic non-destructive method (PUNDIT). Seven coke pieces were heat treated to 1173 K in nitrogen and six showed increases in pulse velocity of 3040%. Ten coke pieces were gasified at 1173 K in carbon dioxide and all showed decreases in puke velocitv of about 10%. The effects of extended heat treatment and gasification are reported.

We conclude that further experiments are necessary to determine whether the very strong indirect evidence for boundary segregation can or cannot be supported directly by experiments on polonium in lead-bismuth alloys.
