摘　　要：利用X射线衍射分析、SEM对Bi2O3-ZnO-B2O3系统低熔点玻璃的烧结性能、玻璃的结晶、烧结后玻璃试样的结构进行了研究。结果表明:随着Bi2O3含量的增加,玻璃试样的烧结收缩率有所增加,烧结变得相对容易,玻璃颗粒液相出现所需要的温度有所降低。该系统低熔点玻璃粉末的烧结是有粘性液相参与的烧结过程,使得玻璃试样的致密化更加有效,效率更高。试样中都析出了-αBi2O3晶相。当温度继续升高时,晶相转变为Bi24B2O39,试样的烧结收缩出现了"滞缓"的现象,试样中有大量的液相出现,试样在表面张力的作用下出现了流散。The sintering property,crystallization and microstructure of Bi2O3-ZnO-B2O3 system low-melting sealing glass are investigated by X-ray diffraction（XRD） and scanning electron microscopy（SEM） in this paper.The results show that as the content of Bi2O3 increases,the sintering shrinkage of the samples is accelerated,and the sintering becomes easy.It needs lower temperature to make liquid phase appear.The crystalline phase is separated out in group A and this phase is α-Bi2O3.With the sintering temperature increasing, the sintering shrinkage of the samples become slower and there are a lot of liquid phase in the ,samples. The ,samples start to flow with the help of the surface tension.
