新型红外玻璃的研制及性质研究 摘要：本文对重金属氧化物玻璃展开了研究，采用差示扫描量热法（DSC）、X射线衍射（XRD）等手段揭示了玻璃在前期制备过程中的结构演变过程。接着对红外玻璃的机械强度、热稳定性、拉曼光谱、红外透过光谱等特性进行了研究。通过改变玻璃组分，研究组分含量变化对玻璃成玻性能的影响,结果表明不同系列玻璃成玻性都有一定的范围；玻璃经热处理后，结构中晶粒长大，玻璃的结构变紧密。玻璃的物理性质的研究结果表明，玻璃的强度和密度与组分的含量有关。通过对玻璃的红外光谱测试得出，随着La2O3含量的上升，红外透过截止波长逐渐向短波迁移，OH-基团的增大导致玻璃红外光谱中吸收峰的增加。本文来自辣&文*论~文'网，毕业论文 www.751com.cn 加7位QQ324,9114找源文

Novel infrared glass manufacture and Properties Study
Abstract :This paper studied the heavy metal oxide glass, the use of differential scanning calorimetry (DSC), X-ray diffraction (XRD) reveals the glass by means of pre-prepared in the course of the evolution of the structure . Then infrared glassof the mechanical strength of glass, thermal stability, Raman spectroscopy, infrared spectroscopy and other properties through the study.The influence of composition changing of the glass on glass forming ability was studied. The results showed that different glasses have their certain glass forming range. The study on physical properties of glass showed that the strength and density of glasses were related to composition. The infrared spectra determing of the glass revealed that infrared cut-off shifted to short-wave with La2O3 content increased in glasses. The absorption peak in infrared spectra of glasses were attributed to the existence of OH- group in glasses.
