1. A lithium silicate glass ceramic for dental restorations, wherein the lithium silicate glass ceramic comprises:
SiO2 from 64 to 75 wt %; and
a main crystalline phase of lithium metasilicate;
wherein the glass ceramic is suitable to be subjected to a heat treatment to convert the main crystalline phase from lithium metasilicate to lithium disilicate and the glass ceramic has a biaxial flexural strength of between 450-820 MPa.
