ESSEN, Germany - Evonik Industries and Jiangsu Zhongneng Polysilicon Technology Development Co. Ltd., a wholly owned subsidiary of GCL-Poly Energy Holdings Limited (GCL-Poly), have signed a letter of intent to establish a joint venture for the production of fumed silica and ultra-pure silicon tetrachloride in China. Evonik will hold a 60% share in the joint venture. The plants, which will have an annual capacity of over 20,000 metric tons, will be built in Xuzhou (Jiangsu Province, China) and are scheduled to start operation in 2016. The entire project has yet to be approved by the executive bodies.
GCL-Poly specializes in the generation of green and conventional energy. Jiangsu Zhongneng is a leading manufacturer of polycrystalline silicon (PCS). Silicon tetrachloride is a byproduct of PCS production, and the joint venture will purchase this to produce AEROSIL® fumed silica and Siridion® STC HP ultra-pure silicon tetrachloride.
