About Us

Zhejiang Guangwei New Materials Co., Ltd. is a high-tech enterprise dedicated to the R&D and production of critical foundational materials for semiconductors. Guided by our technical philosophy of "extreme purity," we have successfully overcome barriers in ultra-high-purity synthesis processes, becoming China's first company to mass-produce 7N-grade ultra-high-purity quartz sand, breaking the long-standing monopoly held by international giants in this field.

The company has established a new entity in Xiaoshan, Hangzhou, and continues to deepen its focus on core sectors such as ultra-high-purity quartz sand and spherical silica. Guangwei New Materials remains committed to long-term growth, leveraging our core strength in independent innovation to build a solid materials foundation for China's self-reliant semiconductor industry.
