Abstract Petroleum pitch‐based graphite blocks (GBs) attract considerable attention owing to their low cost, high yield, and possible application as heat sink components. However, no studies have systematically investigated the particle size distribution of GBs, structures, relationship between structures thermal properties resulting from graphitization. Hence, herein, we present a novel method...

Pile Grade A graphite was used as a moderator and reflector material in the first generation of UK Magnox nuclear power reactors. As all of these reactors are now shut down there is a need to examine the concentration and distribution of long lived radioisotopes, such as 14C, to aid in understanding their behaviour in a geological disposal facility. A selection of irradiated graphite samples fr...

New chloroaluminate compounds with copper and cobalt have been prepared and intercalated into graphite. For the copper intercalated compound X ray analysis shows a chain structure. The magnetic properties are consistent with a model of finite chain distribution

2014 The model of independent graphite subsystems is extended to describe the electronic states in stages 3 and 4 of GAC. The electrostatic effects related to the nonequivalence of the internal and external graphite layers are proved to induce a non uniform charge distribution in the system, and also to modify drastically the band structure. Interband optical transitions are analysed within thi...

Spatially-resolved neutron powder diffraction with a gauge volume of 2 × 2 × 20 mm(3) has been applied as an in situ method to probe the lithium concentration in the graphite anode of different Li-ion cells of 18650-type in charged state. Structural studies performed in combination with electrochemical measurements and X-ray computed tomography under real cell operating conditions unambiguously...

The aim of this work was to synthesize TiC reinforced coating on carbon steel via reduction of ilmenite powder. A mixture of ilmenite and graphite was pre-placed on AISI 1020 steel surface. The effect of the addition of excess graphite amounts on the progress of synthesis of carbide particles was studied. The evolution of phases in different coatings was analysed via X-ray diffraction and scann...
