Neutron Irradiation Induced Changes in the Structure and Properties of Glassy Carbon

The results of an investigation of SU-1300 and SU-2000 glassy carbon samples after irradiation in a BOR-60 reactor at 360-400°C are presented. It is established that substantial radiation compression of glassy carbon under irradiation remains up to neutron fluence 3.6·10^sup 26^ m^sup -2^ (E > 0....

Description
Summary:The results of an investigation of SU-1300 and SU-2000 glassy carbon samples after irradiation in a BOR-60 reactor at 360-400°C are presented. It is established that substantial radiation compression of glassy carbon under irradiation remains up to neutron fluence 3.6·10^sup 26^ m^sup -2^ (E > 0.18 MeV). It is shown that radiation shrinkage is caused by compaction of packets of graphite-like layers and decrease of molecular porosity. Increasing the production temperature of glassy carbon from 1300 to 2000°C decreases the graphitizability of the material under irradiation.[PUBLICATION ABSTRACT]
