- 0 - Abstract of the disclosure Moldings composed of cordierite and a process for producing them For producing moldings composed of cordierite, a batch, which gives the composition of cordierite and contains clay and/or kaolin as well as soapstone and/or talc and also water and an organic aid, is subjected to shear mixing. For this purpose, the batch is placed between 2 bodies, which are at a small distance and move relative to one another, and at the same time the batch is sub- jected to a shear stress. Preferably, the batch is filled into the gap formed by 2 almost touching cylindrical shear rollers which rotate at different speeds or run in opposite directions. The batch is then deformed to give a molding, and the molding is fired until the cordierite phase is formed. Cordierite bodies of very low coefficients of thermal expansion (for example at most 1.1 x 10-6/°C in all three spatial directions) can be obtained.
