    Synthesizing New Anodes From Qatalum's 1st Cut Spl by Hani Holozadah, Abdullah

    Published 2014
    “…The idea is to mix the extracted graphitic material with new binder materials e.g. o-phenylenediamine (C6H4(NH2)2), polyaniline or phosphorous (also a mixture of two or all of them) to increase the thermal and chemical stability and electrical conductivity of these new anodes compared to the currently used anodes in Qatalum (Qatalum uses 70% petroleum coke + 30% Coal Tar Pitch (CTP) as a binder). …”
