초록

A ceramic article which consists essentially, by weight on the oxide basis, of 10-25% SiO2,65-85% Al2O3,and 2-12% Li2O and comprises beta-eucryptite as a first phase having a negative component in thermal expansion and a melting point Tm1,and a second phase having a positive component in thermal expansion which is higher than the component in thermal expansion of the first phase and a melting point Tm2,wherein Tm2>Tm1,wherein the first phase is at most 50% by weight of the ceramic, and wherein the ceramic is characterized by microcracking. Tm2is at least...
