METHOD OF PREPARING INTERCALATION COMPOUND QUASI-MONOCRYSTALS IN GRAPHITE Russian patent published in 1994 - IPC

Abstract SU 1699176 A1

FIELD: technology of intercalation compounds making. SUBSTANCE: method involves successive working of pyrographite with intercalator. Working is carried out firstly in the gaseous phase. Working of pyrographite with iodine monochloride and then with bromine in liquid phase is carried out at temperatures 10-30 K and 30-50 K above its melting points, respectively. Total time of synthesis is diminished up to 24-58 h. Electric conductivity is 10⁷ cm^-1·cm^-1. EFFECT: enhanced quality of quasi-crystals. 3 cl, 1 tbl
