✦ Synopsis

Molten CrO, will intercalate very thin flakes of graphite to give C,, CrO,. The amount in thicker flakes is less, being C,s,CrO, in 2C-25 mesh graphite. The product is stable at 100°C in water and in 6M HCI and does not oxidize a primary alcohol to an aldehyde. The measured increase in thickness during intercalation is in agreement with the X-ray diffraction pattern of the product. Intercalation is confirmed by DTA and by the obvious exfoliation that occurs when the product is heated above the decomposition temperature of CrO, to produce 0, and lower oxides.

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
