摘要：
The invention encompasses a glass-ceramic comprising a continuous glass phase and a crystal phase comprising tetragonal leucite, wherein the glass-ceramic has a crack-free glass phase and a crystal phase comprising leucite crystals distributed essentially homogeneously in the glass phase. The crystal phase has a particle size distribution made of from about 5% to about 70% of a first group of leucite crystals having particle sizes of
