ABSTRACT:
Pitch is converted to mesophase pitch in the presence of catalytically effective amounts of oxides, diketones, carboxylates and carbonyls of metals selected from vanadium, chromium, molybdenum, iron, nickel and cobalt. The crystalloidal or mesophase pitch obtained can be used for the production of carbon fibers and other carbon and graphite products and articles of manufacture of unusually high quality.
