The origin of verious impurities in KRS-5 crystals and the effect of micro-quantity impurities on infrared property have been studied in this paper. Cation impurities and SO_4~(2-) anion in raw materials and KRS-5 crystals were determined by the extraction spectrographic method and the nephe]ometry, respectively. The experiments show that a variety of impurities in KRS-5 crystals mainly come from its raw material and the ppm value of the cation and anion impurities not affects crystal infrared properties,...

The origin of verious impurities in KRS-5 crystals and the effect of micro-quantity impurities on infrared property have been studied in this paper. Cation impurities and SO_4~(2-) anion in raw materials and KRS-5 crystals were determined by the extraction spectrographic method and the nephe]ometry, respectively. The experiments show that a variety of impurities in KRS-5 crystals mainly come from its raw material and the ppm value of the cation and anion impurities not affects crystal infrared properties, and 20ppm of SO_4~(2-) anion in the crystals causes clear impurity absorption peak The determinations of Br-~/I~- ratio in the crystals and the. infrared spectrogram show that the crystal component is not constant and the Br~-/I~- ratio in cystal head is lower than that in crystal tail, and the infrared transmissivity of the head is higher than that of the tail.

本文研究KRS-5晶体中各类杂质的来源及其对晶体红外性能的影响。用萃取光谱法测定晶体及其原料中的阳离子杂质,用浊度分析法测定SO_4~(2-)阴离子杂质。实验表明:KRS-5晶体中的杂质主要来自于原料,ppm级的阳、阴离子杂质对晶片的红外透光性能无太明显的影响;而晶体中20ppm的SO_4~(2-)杂质产生明显的杂质吸收。晶体中Br~-/I~-的化学分析和红外性能测定表明:晶头的Br~-/I~-略低于晶尾,而红外透过率却略高于晶尾。

Nano powders with different mole ratio of Al 2O 3 to SiO 2 have been prepared by hydrolysis precipitation and coating precipitation methods. The chemical composition, crystalline state, morphology and infrared emmision property of the powders have been investigated by ICP, XRD and TEM. The results show that γ Al 2O 3 or Al Si spinel with antispinel structure and vacancy have higher infrared emmisivity in wavelength range of 8~15 μm at room temperatrue.

Nano powders with different mole ratio of Al 2O 3 to SiO 2 have been prepared by hydrolysis precipitation and coating precipitation methods. The chemical composition, crystalline state, morphology and infrared emmision property of the powders have been investigated by ICP, XRD and TEM. The results show that γ Al 2O 3 or Al Si spinel with antispinel structure and vacancy have higher infrared emmisivity in wavelength range of 8~15 μm at room temperatrue. The thin piece particles with low symmetry structure show higher infrared property than the spherical particles and decease of particle size is in favor of improving the infrared property.

In order to improve the stability of glasses, LuF 3 was introduced to fluorogallate glass, which was consisted of 20GaF 3-15InF 3-20CdF 2-15ZnF 2-20PbF 2-10SnF 2, to substitute PbF 2 in the glass. The influences of LuF 3 contents on the thermal property and stability of glasses were studied by differential scanning calorimetry. The infrared property of glasses was studied by infrared transmission spectra. The experiment results indicate that glass has better stability when 2% LuF 3 is added in the glass. And the infrared cut-off wavelength only ranges between 10.1μm and 10.9μm.

以 2 0GaF3 15InF3 2 0CdF2 15ZnF2 2 0PbF2 10SnF2 氟化镓玻璃为基玻璃 ,用LuF3替代等摩尔含量的PbF2 ,以改善玻璃的抗析晶能力。用差示扫描量热法研究了LuF3含量对玻璃热性能和抗析晶能力的影响 ,用红外透过光谱研究了LuF3含量对玻璃透红外性能的影响。结果表明 :在玻璃中掺入摩尔分数为 2 %的LuF3可以获得最佳的抗析晶能力 ;LuF3的掺入对玻璃的透红外性能稍有影响 ,红外截止波长的变化范围仅在 10 .1μm~ 10 .9μm之间。
