Material composition for producing a fireproof material and the use thereof, and fireproof molded body and method for the production thereof

摘要

A method for producing a refractory molded boy using a material composition having a fine-grain fraction with grain sizes of less than 100 mum and a coarse-grain fraction with grain sizes of more than 100 mum. The method includes the steps of adding a dispersing agent and/or a liquefier to the material composition unless the material compositing already includes the dispersing agent and/or liquefier, forming the material composition into a molded body, and sintering the molded body at a temperature above 1300 degrees Celsius.
