中文摘要：
采用DSC、XRD、SEM、FT-IR、维氏显微硬度计和阿基米德法研究了CsCl对Ge23Se67Sb10玻璃特征温度、微观组织,红外透过率、显微硬度和密度的影响规律。研究结果发现,向Ge23Se67Sb10玻璃中加入CsCl,可在玻璃基体中析出GeSe2和Sb2Se3晶体相,析晶相的尺寸随CsCl含量的增加而增大;随着CsCl含量的增加,试样的特征温度降低、密度减小、红外透过率下降;Ge23Se67Sb10玻璃的显微硬度随CsCl含量的增加具有先增大后减小的规律,CsCl含量为2%时,显微硬度达到了208MPa,比基体玻璃提高了近16%。
英文摘要：
By using DSC,XRD,SEM,FT-IR,vickers and archimedes method,the effect of CsCl addition on the characteristic temperature,the structure,the infrared transmittance,the micro-hardness and the density of Ge23Se67Sb10 glass have been studied.It is found that crystallites GeSe2 and Sb2Se3 precipitate in the glass matrix after CsCl is added into the glass.As the CsCl addition increases,the size of the crystallites increases.The characteristic temperature,the density and the infrared transmittance of the Ge23Se67Sb10 glass declines with increasing the CsCl addition.The micro-hardness of Ge23Se67Sb10 glass increases first and then decreases with the increase of CsCl addition.When the addition of CsCl is 2%,the micro-hardness of the sample reaches to 208MPa,which is higher than the base glass by 16%.
