However, its mechanical strength and thermal stability are relatively poor. Therefore, this paper aims to study the microcrystalline strengthening and compression molding technology of Se-based infrared glass.Firstly, we conducted microcrystalline strengthening experiments on Se-based infrared glass samples. By controlling the grain size and distribution of the samples through changing the preparation conditions, the mechanical strength and thermal stability of the samples were improved. The experimental results show that when the grain size of Se-based infrared glass is 10-20 nm, its bending strength and thermal stability are both improved.精品文档---下载后可任意编辑Next, we also conducte...
