摘要
在相同条件下,分别采用石英玻璃坩埚和刚玉坩埚,通过高温熔融-淬火法制备Bi2O3-ZnO-B2O3系无铅低熔点玻璃,利用X射线衍射仪、热膨胀分析仪、X射线光电子能谱、傅里叶红外光谱仪、拉曼光谱等设备测试玻璃粉体,对比不同坩埚熔制Bi2O3-ZnO-B2O3系玻璃粉的异同,分析石英玻璃坩埚和刚玉坩埚对玻璃性能的影响.结果表明:熔制铋酸盐玻璃,配方中SiO2和Al2O3含量少或Bi2O3含量多,使用石英玻璃坩埚熔制获得的玻璃性能优异,实验误差小;若使用刚玉坩埚则会腐蚀坩埚内壁,导致Al2O3进入玻璃液中,虽然改善了玻璃的热稳定性,但会降低玻璃的化学稳定性.
Abstract
Bi2O3-ZnO-B2O3 series lead-free low-melting glass was prepared by high temperature melt-quenching method using quartz glass crucible and corundum crucible under the same conditions.The glass powder of Bi2O3-ZnO-B2O3 series was characterized by X-ray powder diffractometer,Thermal dilatometer,X-ray photoelectron spectroscopy,FTIR spectrometer and Raman spectroscopy.The differences between the Bi2O3-ZnO-B2O3 glass powders melted in quartz glass crucible and corundum crucible were compared,and the effects of two types of crucible materials(quartz glass crucible and corundum crucible)on the properties of the glass were analyzed.The results showed that when preparing bismuthate glass with less SiO2 and Al2O3 or more Bi2O3,using a quartz glass crucible for melting glass with excellent properties and small experimental errors.However,if corundum crucible was used,it will corrode the inner wall of the crucible,leading to the introduction of Al2O3 into the glass melt.While this improved the thermal stability of the glass,it reduced its chemical stability.
