Abstract
To provide a dental lithium silicate glass composition capable of providing a dental lithium silicate glass ceramic capable of efficiently precipitating the main crystals (lithium disilicate and/or lithium metasilicate) even after heat treatment. To provide a AlO-free dental lithium silicate glass composition including the following components: SiO: 60.0 to 80.0% by weight, LiO: 10.0 to 17.0% by weight, KO: 0.5 to 10.0% by weight, ZrO: 0.0 to 5.0% by weight, a nucleating agent: 1.0 to 6.0% by weight, a glass stabilizer: 0.0 to 8.0% by weight and a colorant: 0.0 to 10.0% by weight.
