  • Li2O-Al2O3-SiO2 BASED CRYSTALLIZED GLASS AND PRODUCTION METHOD FOR THE SAME
    Publication number: 20130085058
    Abstract: An object of the present invention is to provide a Li2O—Al2O3—SiO2 based crystallized glass with excellent bubble quality even without using As2O3 or Sb2O3 as a fining agent and a method for producing the same. The Li2O—Al2O3—SiO2 based crystallized glass of the present invention is a Li2O—Al2O3—SiO2 based crystallized glass which does not substantially comprise As2O3 and Sb2O3 and comprises at least one of Cl, CeO2 and SnO2, and has a S content of not more than 10 ppm in terms of SO3.
