Hebei Guiyan Electronic Materials

Hebei Guiyan Electronic Materials Co., Ltd., also referred to as Hebei Silicon Research Electronic Materials, is a high-tech electronic materials company specializing in research and development, production, and technical services. Established in September 2022 as a wholly-owned subsidiary of Shijiazhuang Yousike Electronic Technology Co., Ltd., the company is located in the Shijiazhuang National High-tech Zone Circular Chemical Park. The company's history traces back to 2011 with the founding of Shijiazhuang Yousike Chemical Co., Ltd., which focused on R&D and trade of ceramic adhesives and inorganic materials. A significant milestone was the completion of a Series A financing round in September 2024, securing investments from multiple institutions including a fund under CNOOC Group (Zhongqi Capital), Suzhou Industrial Park Industry Guidance Fund (Oriza Holdings), Xiangjiang Guotou, and Jiangxi Jin控.

The company manufactures a range of products including ultra-high purity silica sol, electronic-grade silicate esters, ultra-high purity silica sol organic dispersion, nano-silica powder, and high-purity synthetic quartz sand. These materials are applied in integrated circuit precision polishing, high-purity coatings, 3D printing, and high-performance organic-inorganic composite materials. A key focus is to address the reliance on American and Japanese manufacturers for high-end grinding particles used in Chemical Mechanical Planarization (CMP) for integrated circuits, aiming to localize the production of these critical materials. The company collaborates with several universities, including Tsinghua University, South China University of Technology, and Hebei University of Science and Technology. Professor Cui Aili from Tsinghua University serves as the Chief Technical Expert of the Silicon Research Institute.

Hebei Guiyan operates as a manufacturer, serving high-tech industries. Its business model is centered on producing and supplying specialized silica-based materials directly to clients involved in advanced manufacturing and electronics. The company's general manager is Weida Qi.
