FIELD: ceramic industry.
SUBSTANCE: invention relates to lithium silicate glass ceramic and glass, which are crystallized at low temperatures and are especially suitable as dental materials, in particular, for dental restoration. Lithium silicate glass ceramics contains hexavalent metal oxide, selected from MoO3, WO3 and mixtures thereof, in amount of 0.1–8.4 wt%, from 12.0 to 20.0 wt% of Li2O and wherein including from 0 to less than 0.5 wt% of K2O. For production of glass ceramics with lithium disilicate as main crystalline phase initial glass with germs is subjected to thermal treatment at temperature of 520–750 °C.
EFFECT: technical result of invention is production of glass ceramic with improved mechanical and optical properties.
