Abstract

PURPOSE: To prepare at a good carbonization yield a molded product with excellent strength and density, by calcining a specified carbonaceous binder and an aggregate after kneading and molding.
CONSTITUTION: A carbonaceous binder obtd. by mixing a heavy oil such as coal tar of atomic ratio H/C ≤1.00 with 6W30% nitrating agent such as nitric acid and an aggregate such as graphite or MgO are kneaded, molded at a temp. ≤250°C, and then calcined.
EFFECT: The resulting binder, having high fluidity during kneading and molding, thermally cures as the molded product is calcined, and is carbonized at an increased yield, wherein the atomic composition of the binder never varies.
