Embodiment Construction

[0011] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the present invention.

[0012] Such as figure 1 As shown, the infrared absorption cell device for measuring the impurity content in titanium tetrachloride of the present invention includes a base 1 and a cover 2 made of glass materials, and the base 1 and the cover 2 are sintered to form a For a pool with an open top, a detection hole 3 is opened on the base 1, and a window 4 is connected above the detection hole 3, and the window 4 seals the detection hole 3. The window 4 made of germanium is used as the seal of the detection hole 3. The window 4 is not easy to deliquescence, corrosion-resistant, and has a transmission wavelength range of 5000cm -1 -800cm -1 , good transmittance and corrosion resistance, so that the present invention has good sealing performance, suitable thickness, easy cleaning, reusa...

Abstract

The invention relates to an infrared absorption cell device used for determining the content of impurities in titanium tetrachloride. The device comprises a pedestal made of a glass material and a seal cover, the pedestal and the seal cover are sintered to form a cell with an open top, the pedestal is provided with detection holes, a window sheet is connected to the top of every detection hole, and the window sheets seal the detection holes. The device ahs the advantages of good corrosion resistance, good light transmittance, simple structure, easiness in dismounting and washing, and repeated use realization.

Description

technical field [0001] The invention relates to an infrared absorption cell device for measuring impurity content in titanium tetrachloride. Background technique [0002] Refined TiCl in sponge titanium production 4 Unqualified quality will affect the quality of sponge titanium, key impurities in sponge titanium and refined TiCl 4 The content of key impurities in the medium has a four-fold enrichment relationship, and the refined TiCl must be 4 In order to ensure the quality of the final titanium sponge, strict quality inspection must be carried out for the key impurities in the product. Remove refined TiCl 4 For the key impurities in the test, it is necessary to quickly and accurately analyze the composition and content of the key impurities. Therefore, refined TiCl 4 The analysis and control of key impurities in the medium is also the key to the quality control of titanium materials, and refined TiCl 4 The detection of key impurity components and their content is the...
