✦ Synopsis

X-ray diffraction, thermal, and chemical techniques have been used to demonstrate that chromium trioxide will intercaiate graphite in the presence of a glaciai acetic acid solvent. The product is a third stage ionic compound of graphite with an identity period I, of 14.92 A, which may be hydrolyzed to give a molecular intercalate. Contrary to previous reports, it appears that chromium trioxide and graphite do not react directly to form an analogous intercalation product, yielding instead a mixture of lower oxides of chromium and unreacted graphite.

The electrochemical behaviour of the dilute intercalation compounds prepared in the reaction of graphite with molten 00, has been examined in 0.25 M H,SO, using a slow (1 mVs\_') potentiodynamic method. The measurements were carried out in a potential range between 0.4 and 1.5 V. Due to deintercalat
