Intercalation of barium into graphite by molten salts method: Synthesis of massive samples for crystal structure determination of BaC6

A solid-liquid method is used to synthesize the first stage bulk BaC6 graphite intercalation compound (GIC). This way of synthesis allows preparation and massive samples useful for crystal structure determination. Through a eutectic medium LiCl–KCl, by submerging platelet in barium-molten solution at 450 °C several days, obtained X-ray diffraction investigations allowed complete structural study. The collected data certify that crystallizes hexagonal P63/mmc space group with following parameters = b 430.6 pm c 1058.2 pm.
