B2O3对中低温硅硼系分相乳浊釉性能的影响
Effects of B2O3on the Properties of the Medium/low-temperature Borosilicate Separated Opaque Glaze System
摘要
Abstract
Effects of B2O3content on the properties of the medium/low-temperature(1200 ℃)separate-phase glaze belonging to the K,NaO-CaO-Al2O3-B2O3-SiO2system was analyzed.The properties and microstructures were characterized by SEM, XRD, FTIR, Vickers hardness and colour test et al.The results indicate that with the increase of B 2O3content,the opacification of glaze increased obviously,and the whiteness of glaze improved with it, and the whiteness reaches the maximum value of 78.7% when the B2O3content is 1.2 mol.But introducing the excessive B 2O3content gave rise to little improving of the glazed opacity,and the flatness and hardness of the glaze also decreased.The results of the SEM and XRD text and the analyse of CaO-B2O3-SiO2phase diagram reveale that the opacification of the glaze is mainly due to the scattering effect of the phase-separated droplets isolated from the matrix phase on the incident light.The increase of B2O3contents is helpful for the formation and coarsening of the droplets and the improvement of the refractive index difference, which strengthened the scattering ability of the glaze on the incident light,and thus the opacification of glaze is enhanced.关键词
