PRODUCTION OF ELASTIC GRAPHITE

Title:

PRODUCTION OF ELASTIC GRAPHITE

Document Type and Number:

Japanese Patent JPH04218590

Kind Code:

A

Abstract:

PURPOSE: To provide a process for producing an elastic graphite having light weight and excellent compressive modulus.

CONSTITUTION: A carbonaceous substance having an atomic ratio of carbon to hydrogen (C/H) of 0.55-4.1 and a softening point of ≥40°C is subjected to a chemical treatment to increase the nitrogen content by ≥2.0wt.% and increase the oxygen content by ≥20.0wt.% determined by the elemental analysis of the carbonaceous substance. The chemically treated carbonaceous substance is heat-treated to obtain the objective elastic graphite.
