摘要: 作为一种重要的中长波红外窗口材料,元素级ZnS具有良好的光学性能和力学性能。目前,高超声速飞行器的发展迫切需要开展元素级ZnS红外窗口的高温性能研究。本文研究了不同温度下元素级ZnS的高温性能,结果表明,元素级ZnS的辐射率随着波长增大而增加,且同一波长下随温度的升高而增加,500 ℃时,在3~5.5 μm平均法向光谱辐射率小于0.05,7~10.5 μm平均法向光谱辐射率小于0.10。在2~9.5 μm,温度对透过率影响并不大,在9.5 μm后,随着温度的升高,透过率明显降低。折射率、热光系数和线膨胀系数随温度的升高而增大。温度对弯曲强度几乎无影响,弹性模量随温度升高而降低,800 ℃时的弹性模量与室温下的相比下降约30%。

Abstract: As a kind of medium and long wave infrared optical material, elemental ZnS has excellent optical and mechanical properties. At present, the development of hypersonic vehicle urgently requires research on the high-temperature performance of elemental ZnS infrared windows.The high-temperature performance of elemental ZnS at different temperatures were studied in this paper, and the results show that the emissivity of elemental ZnS increases with the increase of wavelength, and increases with the increase of temperature at the same wavelength. At 500 ℃, the average normal optical spectrum emissivity is less than 0.05 at 3~5.5 μm, and less than 0.10 at 7~10.5 μm. In the range of 2~9.5 μm, the temperature has little effect on the transmittance, but after 9.5 μm, the transmittance decreases significantly as the temperature increases. The refractive index, thermal optical coefficient, and expansion coefficient increase with increasing temperature. Temperature has almost no effect on bending strength. The elastic modulus decreases with increasing temperature, the elastic modulus at 800 ℃ decreases by about 30% compared to that at room temperature.
