Abstract

PURPOSE: To enable mass production of exfoliative graphite by oxidizing 65W98% C-contg. graphite of specified mesh with an oxidizing agent such as chromic acid and by forming salt with sulfuric acid or the like after which the treated graphite is mixed with a refractory, washed, and dried.
CONSTITUTION: 65W98% C-contg. flake graphite of 10W80 mesh is treated with a soln. of chromic acid, permanganic acid, potassium permanganate, phosphoric acid, manganese dioxide or the like, and sulfuric acid or phosphoric acid is mixed into the oxidized graphite to form salt in the openings. After reaction for a predetermined time an adequate amt. of a fire resistant or insulating filler such as calcined alumina is added to the treated graphite and mixed until the mixt. is dried. The mixt. may be washed with water and dried. the resulting exfoliative graphite can be expanded by 300 times when it receives a temp. impact, and mass production of the exfoliative graphite suitable for use as an insulator for metallurgy, etc. is enabled.
