Shaanxi Nonferrous Tianhong Ruike Silicon Materials Co., Ltd. (hereinafter referred to as the "Company") is a Sino-foreign joint venture high-tech enterprise integrating ultra-pure silicon material manufacturing, sales, services and research and development. The company was jointly funded by Shaanxi Nonferrous Metals Holding Group Co., Ltd., a wholly-owned subsidiary of Shaanxi Nonferrous Metals Holding Group Co., Ltd. and REC Silicon Inc., a world-leading silicon material manufacturing company. It was officially established in July 2014 and registered. With a capital of US$498 million, Shaanxi Nonferrous Metals Tianhong New Energy Co., Ltd. and US REC Silicon Inc. hold 84.94% and 15.06% of the company's shares respectively.

The company is located in Yujia Economic and Technological Development Zone, making full use of Yulin’s local advantageous resources, guided by the implementation of the central government’s spirit on scientific development and the provincial party committee and government’s accelerating the construction of energy and chemical bases in northern Shaanxi, and takes the “coal-electricity-silicon” industrial chain as Relying on the introduction of the world's leading electronic-grade polysilicon, electronic-grade silane gas and granular polysilicon production technology of REC Silicon in the United States, we will build a silicon material production line with an annual output of 500 tons of electronic-grade high-purity silane gas, 1,000 tons of electronic-grade polysilicon, and 18,000 tons of granular polysilicon. After completion, the annual output value will reach RMB 4 billion.

The company adheres to the production and operation philosophy of green, low-carbon, win-win cooperation and giving back to the society. The silane fluidized bed (FBR) technology used to produce granular silicon can significantly reduce the production cost of polycrystalline silicon and provide downstream enterprises with high-quality and low-priced raw materials, while also achieving continuous single crystal drawing of downstream enterprises and effectively increasing the single casting of ingots. Furnace output, improve productivity, enhance market competitive advantages, and achieve mutual benefit and win-win results. The quality of electronic-grade polysilicon and electronic-grade silane gas produced by the company has reached the international leading level, which not only fills the domestic gap, but also greatly improves the supporting capabilities of our province's silicon materials industry and Samsung projects, and promotes Shaanxi Province to become a complete domestic industrial chain and advanced technology. semiconductor base.

Faced with the fierce market competition environment and the new normal of economic development, the company will rely on the new Sino-foreign joint venture platform to create a new model of scientific management, achieve a high starting point, high standards, high quality and high efficiency, highlight innovation-driven, optimize production and operation, and achieve The company will develop healthily and sustainably, establish, enhance and consolidate the company's leading position in China's silicon materials industry, and build a large silicon materials company with international competitiveness.
