The preparation and refining process of silicon tetrachloride were mainly introduced. The industrial preparation methods of silicon tetrachloride mainly include silicon iron chloride method, waste contact chlorination method, silicon hydrogen chloride method, silicon dioxide chlorination method, etc. The characteristics of each method were introduced separately. The refining methods mainly include adsorption method, reaction method, distillation method, and a combination of these methods. Fiber grade high-purity silicon tetrachloride can be obtained by using a two-stage distillation method, At the same time, the filling and quality standards of high-purity silicon tetrachloride were introduced. In addition, the application, economic overview, and prospects of silicon tetrachloride were briefly introduced
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. proposed the gas chromatography method for determining the purity of silicon tetrachloride. Using SE-30 stainless steel packed chromatographic column for separation, thermal conductivity detector detection, and area normalization method for quantification. The method is used to analyze silicon tetrachloride standard samples. The relative error between the measured value and the standard value is O.18%, and the relative standard deviation (n=5) is O.12%.
