Molecular formula : MW : CAS :
nature : for the alkali metal atoms embedded graphite layer formed between the intercalation compounds. With the composition of reaction conditions vary : C + M �C60M �C48M �C36M �C24M �C8M color as gray, blue and gray, blue, steel blue and discarded. C8K the crystal structure shown in Fig, the potassium atoms occupy triangular position. Graphite-alkali metal compounds conductivity higher than that of graphite. Combustion in air, water violent reactions or even explosive. In some organic synthesis for the reductant. The advantage of easy separation by filtration. A small drawback is prone to air or water decomposition, and as a multiphase reactions. Potassium, rubidium, cesium and graphite easy direct response to lithium or only at high temperature under high pressure, it is difficult to directly sodium and graphite reaction.
