This invention relates to a refractory ceramic batch and to a method for producing a refractory ceramic product.

The invention relates to a batch composition for producing a refractory product, a method for producing a refractory product, a refractory product, and to the use of a synthetic raw material.

A refractory article includes a body having a first portion defining at least a portion of a first exterior surface of the body, the first portion including a carbide, and further including a second portion defining at least a portion of a second exterior surface of the body opposite the first exterior surface, the second portion including an oxide, and a thermal conductivity difference (ΔTC) of at least 10 W/mK between the first exterior surface and the second exterior surface, and an average Shell Temperature of not greater than 400° C.
