摘要
采用了高温熔融法制备了Bi_2O_3-B_2O_3-ZnO-Al_2O_3-SiO_2系银浆玻璃玻璃粉,添加少量CeO_2作稳定剂,分别采用铂金坩埚、石英坩埚、刚玉坩埚在1100℃条件下熔制,系统研究了在不同坩埚熔制时对该系玻璃的玻璃化程度、热学性能及化学稳定性的影响。结果表明:在添加CeO_2稳定剂的前提下,该系玻璃在铂金坩埚、石英坩埚、刚玉坩埚中均能熔制出均匀透明玻璃。在铂金坩埚中熔制时,玻璃的玻璃化程度较高。在石英坩埚中熔制时,较多的SiO_2融入该系玻璃粉内,提高了其玻璃化转变温度,但其膨胀系数明显降低,其热稳定性与化学稳定性也有大幅度提高。在刚玉坩埚中熔制时,刚玉坩埚中少量Al_2O_3融入玻璃粉内,提高了该系玻璃粉的玻璃化程度,对其热稳定性与化学稳定性的提高也有一定的促进作用。
Bi2O3-B2O3-ZnO-Al2O3-SiO2 positive silver glass frit powder was prepared by high temperature melting method.Add a small amount of CeO2 as a stabilizer,Melted at 1100 using platinum,quartz and corundum respectively.The effects of the degree of vitrification,thermal properties and chemical stability of the glass on the different crucibles were investigated systematically.The results show:under the premise of adding CeO2 stabilizer,the glass can be melted into uniform transparent glass in platinum crucible,quartz crucible and corundum crucible.When molten in platinum crucible,the degree of vitrification of the glass is high.When melting in quartz crucible,more SiO2 is incorporated into the glass frit,which increases the glass transition temperature,but can significantly reduce its expansion coefficient,and its thermal stability and chemical stability are also greatly improved.When melted in corundum crucible,a small amount of Al2O3 in the corundum crucible is incorporated into the glass frit,which improves the vitrification degree of the glass frit,and also promotes the thermal stability and chemical stability.
