Process for manufacturing glasslike carbon material.

摘要

A process for manufacturing glasslike carbon material is disclosed in which a thermosetting resin, which exhibits hydrophilic properties and is capable of containing a least 20% by weight of water and has a viscosity in the range of from 100 to 8000 cps (at 25 DEG C), is carbonized and sintered in an inert atmosphere at a temperature of at least 800 DEG C. A molded product which is manufactured according to the invention process and which is useful as a substrate for a magnetic head is also disclosed.
