Abstract
DURING an X-ray diffraction investigation of the potassium graphites1, we concluded that the reduction in potassium concentration within the intercalate layer, which occurs on passing from stage 1 (C8K) to stage n (C12nK), is accompanied by a loss of long range order within the layer. A study of the stage 2 compound has now shown that this disordered intercalate structure (form I) transforms reversibly to an ordered state (form II) at a temperature of about −175°C.
