超純硅的好壞，往往取決于原料的純度。超純硅的發(fā)展方向是如何進(jìn)一步提高純度效果。精餾法是一種最重要的提純方法，此法具有處理量大，操作方便，板效率高，又避免引進(jìn)任何試劑，絕大多數(shù)雜質(zhì)都能被完全分離，特別是非極性重金屬氧化物。精餾搭的操作是從物料平衡，氣液平衡，熱量平衡及精餾塔性能等幾個發(fā)面考慮，通過控制系統(tǒng)建立并調(diào)節(jié)塔的操作條件。

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.
