超纯硅的好坏，往往取决于原料的纯度。超纯硅的发展方向是如何进一步提高纯度效果。精馏法是一种最重要的提纯方法，此法具有处理量大，操作方便，板效率高，又避免引进任何试剂，绝大多数杂质都能被完全分离，特别是非极性重金属氧化物。精馏搭的操作是从物料平衡，气液平衡，热量平衡及精馏塔性能等几个发面考虑，通过控制系统建立并调节塔的操作条件。

The quality of ultrapure silicon often depends on the purity of the raw material. The development direction of ultra pure silicon is how to further improve the purity effect. Distillation method is the most important purification method, which has a large processing capacity, convenient operation, high plate efficiency, and avoids the introduction of any reagents. The vast majority of impurities can be completely separated, especially non-polar heavy metal oxides. The operation of distillation tower is considered from several aspects such as material balance, gas-liquid balance, heat balance, and distillation tower performance. The operating conditions of the tower are established and adjusted through a control system.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses gas chromatography, DC550 packed column, and thermal conductivity detector to determine the purity and impurities of industrial trichlorosilane. The column efficiency is high, the separation is good, and the results are satisfactory.
