Abstract
A ceramic product comprising both carbon and nitrogen and a method for its production are provided. The product is formed in a reactor having a chamber defined therein which is divided into a combustion zone and a reaction zone. A combustible mixture is injected into the combustion zone in a direction generally toward the reaction zone, and is accordingly combusted in the combustion zone to produce hot combustion products. At least one reactant containing carbon, nitrogen and an additional component (i.e. silicon) is injected at the boundary between the zones into the reactor chamber so as to flow with the hot combustion products into the reaction zone and react to form the ceramic product.
