The Melting Crystallization and Fluidity of SiO2-B2O3-Al2O3-TiO2 Frit for Enamel Glaze

Abstract

The influence of temperature on the crystallization and the melting of the glassy frit was discussed. SiO 2 -B 2 O 3 -Al 2 O 3 -TiO 2 frits were obtained by melting batches at different temperatures, were investigated by DTA and the crystallization energy was calculated. The fluidity of the frits upon heating was estimated based on the sintering images. XRD measurements were applied to identify the crystalline phase of the sintered frits. The results show that the frit has reduced activation energy when the melting temperature is high. However, the melting temperature does not have effects on the transition and crystallization temperatures of the glass frit. Although the frit could crystallize at a low temperature, a much higher temperature has to be used for the sintering of the frit to obtain enamel glaze with a high flatness.
