Abstract

A molded, fireproof product, which contains graphite, in particular natural graphite, and is based on fireproof granular materials. The granular-material grains of the product are consolidated to form a molded body by means of a binder known per se and/or ceramic bonding. The product has a homogeneous mixture of at least two graphite types, which each have a different coefficient of thermal expansion. One graphite type is predominant by amount and the other graphite type acts as an auxiliary graphite type. The invention further relates to a method for producing a product and to the use of the product.
