In order to determine the relationship between the composition and glass transition temperature of the metal melt,solve the problem of the amorphous formation ability of metal and the accurate design of the amorphous material components,the optical properties and characteristic temperature of Ge-Se chalcogenide glass were studied.The samples of good compactness of GeSe4 and GeSe8 glass were prepared by the method of the melt-quenched.By the Fourier transform infrared spectrometry,the infrared transmittance of the sample was measured.The refractive index n of the two samples was calculated by the approximate linear relation equation.With the method of differential scanning thermal analysis,the glass transition temperature T g of the sample was measured.The dynamics ideal glass transition temperature T 0g of the specimen was fitted by VFT equation.The results show:The infrared transmittance is about 60%,indicating that the infrared performance is good.The refractive index of the GeSe4 and GeSe8 sample in 3 μm and 10 μm are respectively 2.558 5 and 2.463 0,2.599 4 and 2.481 8.The glass transition temperature T g and the dynamics ideal glass transition temperature T 0g of the sample were respectively 161.33 ℃ and 98.99 ℃,161.33 ℃ and 98.99 ℃.
