The present invention relates to an improved cordierite glass-ceramic. In order to improve the materials properties, it is proposed that the glassceramic comprising Si02, AbOs, MgO and Li20 contains cordierite as main crystal phase and that a secondary crystal phase of the glass-ceramic comprises high-quartz solid solution and/or keatite solid solution. The invention further relates to a process for producing such a glass-ceramic and the use of such a glass-ceramic. |
