摘 要:采用高温熔融水淬的方法,制备了w(Bi2O3)为50%~65%,w(B2O3)为25%~40%的Sb2O3掺杂Bi2O3-B2O3系玻璃粉体,研究了Bi2O3和B2O3含量对所制玻璃的玻璃转变温度tg、软化温度tf、线膨胀系数αl以及电阻率ρ等的影响。结果表明,随着w(Bi2O3)的增加,玻璃的tf缓慢下降并维持在490℃左右,熔封温度为550~600℃,αl从62.3×10–7/℃上升至69.1×10–7/℃;在80~200℃,玻璃的ρ为1011~1013Ω·cm。Sb2O3 doped Bi2O3-B2O3 glass powders, in which the contents of Bi2O3 and B2O3 were 50-65wt% and 25-40wt% respectively, were prepared through high-temperature melting, water quenching and grinding. The effect of the contents of Bi2O3 and B2O3 on the glass transition temperature tg, soft temperature tf, linear expansion coefficient at and resistivity 19 of prepared glass was studied. The results show that, with increasing Bi2O3 content, the tf of prepared glass decreases slightly and levels off at about 490℃, making the sealing temperature be in a range of 550-600 ℃, while the at increases from 62.3×10^-7/℃ to 69.1×10^-7℃. At 80-200℃, the ,ρ of prepared glass is in a range of 10^13-10^11 Ω.cm.
