Abstract

We prepared a borosilicate glass, in which the ZrO₂ phase is singly crystallizable, i.e., 15Na₂O–15ZrO₂–30B₂O₃–40SiO₂ glass, and investigated the texture and morphology of the resulting glass-ceramics. ZrO₂ dendrites with a tetragonal system (high-temperature phase) were developed as initial phase, and the tetragonal phase was transformed to the monoclinic phase (low-temperature phase) by elongation of the heat-treatment time, and finally the needle-/rod-like crystals on a scale of few hundred nanometers were obtained. The glass-ceramics with monoclinic ZrO₂ showed photoluminescence around 480 nm by excitation in the ultraviolet region. The effect of TiO₂-addition on the photoluminescent property was also considered.
