The production and application of carbon bonded refractories is linked with environmental harmful emissions in the broadest sense. Amongst the aspect of environmental friendly refractory systems this work has observed and shown the interaction of functional ceramic material TiO2 with the organic binder system in doloma carbon refractories. The focus of the present work lays on increased residual carbon content of the binder resin and furthermore improved mechanical and physical properties due to TiO2-addition. This offers the feasibility to reduce the total carbon content without downgrading the brick properties. This aspect has not been observed yet and is of high interest with respect to reduced emissions and environmental friendly refractories.
