Bonded Bulk Graphite and Process for Bonding.

reportActive / Technical Report | Accession Number: ADD009050 | Need Help?

Abstract:

Bulk pieces of graphite bonded with a graphitizable binder comprising a liquid crystalline component of pitch, which softens at about 240 C and becomes very fluid at about 300 C to about 500 C. The bonded graphite pieces appear as a monolithic material even under 1000x magnification. The bonding is effected under vacuum or in an inert atmosphere at temperatures of from about 700 C to about 3000 C, usually about 1000 C to about 1500 C, under pressure of from about 20 psi to about 1000 psi applied in a direction normal to the bonding surface.
