The crystallization behavior of lithium and sodium disilicate glasses obtained by quenching melts held at different temperatures was determined. Holding the glass melts at different temperatures was found to affect crystallization in these glasses. An optical microscope observation showed that the precipitated LS needles and LS2 crystals increased in number as the holding temperature decreased. Taking into account that LS crystal cannot form without the existence of Pt, the LS precipitation behavior depending on the holding temperature represents the distribution of Pt colloids formed during the holding of the melt at different temperatures. Additionally, XRD measurements showed that the glass held at just above the liquidus temperature had high crystallinity of LS compared with that held at 1350 °C. The holding temperature dependence of LS2 crystallinity was identical to that of LS crystallinity in 0.55 L and 0.6 L compositions. However, the crystallization of LS2 was markedly elevated in 0.65 L glass, and the higher holding temperature resulted in greater crystallization than the lower holding temperature. It is not known exactly why such crystallization advances, but the structural change in the matrix glass depending on the holding temperature of the melt affects the crystallization.
