โฆ Synopsis
C-14 labelled graphite has been used to demonstrate that positively charged ions (probably CO*+) play a significant role in the oxidation of graphite by ~-radiolysed carbon dioxide. About 40 per cent of the total reactivity is attributed to ions.

A study has been made of the effect of radiolytic oxidation by carbon dioxide on the porosity of 'A' grade pile graphite ('P.G.A.') and also a material of lower initial porosity designated CPsRsG. Use of in-pile rigs operated at 735 lb/in\* (gauge) enables weight losses up to 29% to be obtained. Res
Graphite samples have been exposed to carbon dioxide irradiated with ionizing and non-ionizing radiation. Observations made in an electron microscope of selected areas of graphite before and after exposure to oxidizing species show, at one end of the scale, complete resistance to attack and, at the
IN A previous paper(r) the effect of iodine on the oxidation of graphite of high purity was reported to be an accelerating one. To elucidate this effect the dependence of the oxidation rate upon the pressure of iodine has been studied. Experimental procedures and apparatus have been described in th
The radiolytic oxidation of graphite in carbon dioxide cooled nuclear reactors is of great practical importance, but direct measurements of the oxidation of pores are very difficult. Progress has recently been made by studying the changes in permeability of graphite and the diffusivity ratio with ox
