摘要：
The invention relates to a lithium silicate glass ceramic, which contains at least lithium disilicate as a crystal phase, and lithium aluminum silicate as further crystal phase. The lithium silicate glass ceramic in its initial composition contains Al2O3 at 1.5 to 3.5 percent by weight, and K2O at 0.6 to 1.8 percent by weight.
