✦ Synopsis

The decomposition of polytetrafluorethylene contacting O-9 at. % G-amalgam at ambient temperature is described. The reactio; has the character of corrosion penetrating into depth; its course is elucidated on the basis of an electrochemical mechanism. The lithium amalgam functions as anode of a galvanic corrosion cell and polytetrafluorethylene as cathodic depolariser. The operation of the cell results in the formation of a solid electrolyte, a molecular dispersion of carbon and lithium fluoride, possessing electronic as well as ionic conductivity at 20°C.
