SYNTHESIS OF INTERCALATION COMPOUNDS OF ALKALI-METAL ATOMS AND A HALOGEN MOLECULE WITH QUASI-ONE-DIMENSIONAL CARBON CRYSTAL CARBOLITE

Alkali metal atoms and a halogen molecule have been intercalated in qu asi one dimensional carbon crystal ''carbolite''. Carbolite was synthe sized by quenching carbon are on copper plate or sapphire plate at. th e room temperature. Linear carbon chains were generated by quenching a nd arrayed in a direction perpendicular to the substrate plate. The tr iangularly distributed array was a coarse aggregation oi chains by the van der Weals force. Therefore it was expected that the intercalation of, for example, an alkali metal atom was possible similarly to the g raphite intercalation. The in-situ change of the electrical resistance of intercalated carbolite by the heat treatment has been investigated . The temperature dependance of the resistance has shown a thermal act ivation type.
