Abstract

Abstract: First stage strontium-graphite intercalation compound (GIC) is successfully synthesized using a recent method based on eutectic medium LiCl–KCl. The bulk compound is obtained after immersing a graphite platelet in strontium-molten salt solution at 450 °C for several days. Using such bulk GIC, an accurate structural study is performed by applying X-ray diffraction techniques (00 l, hk 0 and rotating crystal method). It is validated that SrC6, similarly to most MC6 compounds, crystallizes in a hexagonal P 63 /mmc space group with subsequent parameters a = b = 431 pm and c = 988 pm Graphical abstract: Image 1
