Yichang Nanhua Silicon Materials Co., Ltd. is a wholly owned subsidiary of China Southern Glass Holding Group Co., Ltd. (Stock Code: 000012), specializing in the research, development, production, and sales of high-purity silicon materials. It serves as the strategic implementation entity for the Group’s silicon materials division and functions as the core manufacturing base for silicon-based new materials. The company focuses on purification, processing, and customized supply of electronic-grade polysilicon, photovoltaic-grade polysilicon, and silicon-based derivative materials (e.g., silicon powder, spherical silicon micro-powder, etc.). Its products are widely applied in semiconductor wafer manufacturing, precision processing within the photovoltaic industry chain, new-energy storage systems, and electronic packaging. Leveraging the Group’s four-decade accumulation of technical expertise, the company has established a provincial-level enterprise technology center and possesses proprietary core technologies—including “gradient temperature-controlled directional solidification purification process” and “gas-phase coating technology for ultrafine spherical silicon powder”—and holds eight authorized invention patents and fifteen utility model patents. Its electronic-grade polysilicon achieves a purity level of 11N (99.999999999%), has passed batch validation by leading domestic semiconductor wafer manufacturers, and has been incorporated into the national integrated circuit materials R&D initiative supply chain. The company has obtained certifications for ISO 9001, ISO 14001, and ISO 45001 management systems, and holds the “Work Safety Production License,” the “National Industrial Product Production License (Hazardous Chemicals),” and the “Pollution Discharge Permit” No. EYiHuanXu [2024] 078. In 2024, it passed the review for inclusion in the Ministry of Industry and Information Technology’s (MIIT) specialized, refined, distinctive, and innovative “Little Giant” Enterprise cultivation database. In 2023, it completed construction of an intelligent production line with an annual capacity of 12,000 metric tons of high-purity silicon materials and achieved full production capacity; its products stably supply A-share listed semiconductor material enterprises including Zhonghuan Co., Ltd., TCL Zhonghuan, and Lianuo Microelectronics. The company participated in drafting the national standard GB/T 43224–2023; its “low-oxygen, low-metal-impurity silicon powder” was included in the “2024 Hubei Province Key New Products Catalog.” Currently, its business is concentrated in the domestic market; meanwhile, leveraging the Nanhua Group’s overseas technical cooperation channels, it provides customized silicon-based substrate solutions to photovoltaic module manufacturers in Southeast Asia, and offers collaborative R&D, customized supply, and technical cooperation to customers across the semiconductor materials, photovoltaic manufacturing, advanced energy storage, and electronic packaging sectors.
