Title:
GRAPHITE PRODUCTION METHOD AND PRODUCTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/183911
Kind Code:
A1
Abstract:
In a graphite production method for producing graphite of superior quality, if the highest temperature in the heating oven is brought to 2,900°C or higher, a discharge occurs between a heater and a graphite container, so electric power cannot be converted efficiently into heat of an electric heater. The objective of the present invention is to provide a graphite production method for producing graphite of superior quality. A graphitization step includes setting the distance between the graphite container and the heater within a specific length range, turning the gas within the heating oven into an atmosphere containing helium gas, and heating the interior of the heating oven in such a manner that the highest temperature therein reaches 2,900°C or higher. Accordingly, graphite of higher thermal diffusivity is achieved.
