It is shown that the introduction of antimony oxide Sb2O3 into the makeup of lithium-aluminum-silicate glass with sitall-forming composition makes it possible to suppress the often observed cracking of the glass during its crystallization at temperatures above 700°C. It was found that the introduction of Sb2O3 does not change the phase composition of the formed sitall. A scenario describing the observed effect is proposed for the implantation of antimony atoms into the residual glass phase.
