随着太阳能这一绿色能源的开发和利用，多晶硅作为光伏电池的原料得到了越来越广泛的应用，在生产多晶硅的方法中，西门子是最受欢迎的一种，在生产多晶硅原料三氯氢硅的同时，也会产生大量的副产品四氯化硅，回收四氯化硅的方法很多，如制气相二氧化硅、合成有机硅产品、制造高纯光纤、锌还原、最佳方法是四氯化硅加氢制备三氯氢硅。
With the development and utilization of green energy-solar energy,polysilicon,as a raw material of photovoltaic battery is used more and more widely.Among the methods for producing polysilicon,Siemens is the most popular one.While producing trichlorosilane which is the raw material of preparing polysilicon,a large amount of silicon tetrachloride as by-products is also manufactured,which has serious pollution to the environment.So how to deal with these by-products has become an urgency problem to solve.Many methods for recycling silicon tetrachloride,such as making fumed silica,synthesizing organosilicon products,manufacturing high-purity optical fiber,reducing by zinc,etc.The best method is hydrogenation of silicon tetrachloride to prepare trichlorosilane.
