【摘要】 Bi₂O₃-ZnO-B₂O₃是一种新的玻璃系统,本文采用传统的熔融冷却工艺对Bi₂O₃-ZnO-B₂O₃三元系统成玻区域进行了研究,讨论了组成对成玻区域以及其热性能的影响。采用XRD对其成玻性能进行表征,DSC用于研究组成对热性能的影响情况,同时还研究了不同组成玻璃的密度的变化情况。结果表明:B₂O₃容易引起分相,所以富硼区域很难成玻,Bi₂O₃-B₂O₃成玻区域较ZnO-B₂O₃成玻区域大;Bi₂O₃含量的增加能降低玻璃的转变点温度,而ZnO、B₂O₃则使之升高;玻璃的密度随Bi₂O₃含量增加而增大。更多还原

【Abstract】 Bi₂O₃-ZnO-B₂O₃ glass as a new kind of glass system was investigated by traditonal melting and cooling process using Bi₂O₃、ZnO and boracic acid（H₃BO₃） ofanalytical purity as rawmaterials,besides the glass forming region and its thermal property were discussed.Glass forming property was characterized by X-ray diffraction（XRD）, The feature temperature was characterized by differential scanning calori metry（DSC）,otherwise volume density was also measured for investingating.The results showed that glass was prone to phase separation caused by B₂O₃,so that the region which highly contained with B₂O₃ was hard to forming glass,Bi₂O₃-B₂O₃ glass forming range was more greater than ZnO-B₂O₃ area;the transition temperature of the glass decreased with the content of Bi₂O₃ increase, whereas was contrary to ZnO、B₂O₃ content;volume density of the glass was increased with content of Bi₂O₃ increase.更多还原
