Graphite-like layered material of composition BC2N was prepared by the CVD reaction of acetonitrile with boron trichloride at 2070 K. Sodium was intercalated into the BC2N film and powder by two methods: a vapor phase reaction and an electrochemical method. The first stage compounds were prepared by the vapor phase reaction using the BC2N film and powder. A mixture of the first and the second stage compounds was prepared from the BC2N powder, while the first stage compound was prepared from the BC2N film by the electrochemical method. The d-spacing of the intercalated layers was 0.43 nm, calculated from the sharp (0 0 1) and (0 0 2) diffraction lines observed on the X-ray diffraction patterns of the first stage compounds prepared from the BC2N films by the two methods.

SGL CARBON GmbH The commercialization of carbon fibers and their composites initially served the defence and aerospace industry. Sporting goods followed and allowed carbon fiber companies to survive the years after the cold war. High prices and manual production technologies hindered entrance into big consumer markets. This situation is going to change with the implementation of highly automated textile processes for the production of carbon fiber reinforced polymers (CFRP). The biggest impetus is coming from the energy and CO2 debate. Thus CFRP components will further grow in the aviation industry but also spread into automobiles, windmills, civil engineering and other industrial applications. The carbon fiber market is dominated by producers based in Japan and in the USA, with precursor production in the hands of Japanese companies. Europe has failed to build home-based precursor and carbon fiber production technologies. SGL Group – The Carbon Company as a leader in the carbon and graphite
