SnO对ZnO-Sb_(2)O_(3)-P_(2)O_(5)玻璃结构与性能影响

Effect of SnO on the structure and properties of ZnO-Sb_(2)O_(3)-P_(2)O_(5) glass

以40P_(2)O_(5)-32.5Sb_(2)O_(3)-27.5ZnO三元系统玻璃为研究基质,SnO从摩尔分数1%开始,每次以1%递增取代ZnO制备ZnO-SnO-Sb_(2)O_(3)-P_(2)O玻璃。利用FT-IR、DTA、膨胀仪对玻璃的结构与性能进行表征,研究添加SnO对玻璃形成、结构和玻璃热膨胀系数、转变温度等性能的影响。结果表明,过量的SnO会导致玻璃失透,玻璃中SnO的摩尔分数最多为3%。引入适量的SnO能生成O—Sn—O键进入玻璃网络结构,能够提高玻璃的耐水性;玻璃的转变温度与膨胀系数随着SnO的增加而上升。

Using 40P_(2)O_(5)-32.5Sb_(2)O_(3)-27.5ZnO ternary system glass as the base matrix, ZnO-SnO-Sb_(2)O_(3)-P_(2)O glass was prepared by replacing ZnO with SnO starting from the molar ratio of 1% and increasing by 1% each time. The structure and properties of glass were characterized by FT-IR, DTA and dilatometer. The effects of SnO addition on glass formation, structure, thermal expansion coefficient, transition temperature and other properties were studied. The results showed that excessive SnO addition would lead to glass opacity, and the amount of SnO added to the glass studied was up to 3%. O—Sn—O bonds in the glass network structure can be produced by an appropriate amount of SnO addition, and the water resistance of glass can be improved. The transition temperature and expansion coefficient of the glass rise with the increase of SnO.
