In an Li2O-Al2O3-SiO2 transparent crystallized glass, .beta.-quartz solid solution is produced as main crystals, an average coefficient of linear thermal expansion within a range between 30 and 380°C is -10~10 X 10- 7/°C, and .beta. - OH in an amount of 0.28/mm or more is contained. Preferably, the content of each component of Li2O, SiO2, and Al2O3 satisfies, by weight ratio, the relationship given by 0.058 ~{Li2O/(SiO2 + Al2O3)} ~ 0.031.
L'invention concerne un verre transparent cristallisé de type Li2O-Al2O3-SiO2 pouvant précipiter une solution solide de quartz bêta, en tant que cristal principal, qui possède un coefficient moyen d'expansion thermique linéaire dans la plage comprise entre 30 et 380 DEG C de -10 x 10<-7> à 10 x 10<-7>/ DEG C, et contient au moins 0,28/mm de beta -OH. De préférence, le rapport en poids de la teneur en Li2O-Al2O3 et en SiO2 satisfait la relation 0,058 >/= {Li2O/(SiO2 + Al2O3)} >/= 0,031.
