Infrared absorption cell device used for determining content of impurities in titanium tetrachloride

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...
