Carbon blacks can be graphitised to different degrees, whereas glassy (vitreous) carbons, which are used as electrode material, in electronics and construction, and as crucibles, are resistant to graphitisation. Recently we have investigated the proton dynamics of type 1 glassy carbon as a non-graphitising carbon (maximum service temperature under argon: 1000°C) on TOSCA. The aim of this proposal is to extend the study to type 2 glassy carbons (for maximum service temperature under argon: 3000°C) and to compare this to ordered and disordered acetylene blacks (very clean, high sp2 character).
