China's Ministry of Natural Resources has unveiled a groundbreaking discovery: a new mineral species, high-purity quartz ore, crucial for advancing semiconductor and photovoltaic technologies. Extracted from rocks that yield silicon dioxide with a purity of no less than 99.995%, this mineral meets the rigorous demands of high-tech applications.
The discovery, part of a strategic mineral exploration initiative across the Chinese mainland, has identified promising deposits in the eastern Qinling Mountains of Henan Province and Altay in the Xinjiang Uygur Autonomous Region. Experts say this breakthrough not only reduces reliance on imports but also fortifies the resilience and security of industrial supply chains.
Innovative research by numerous enterprises and institutions has already led to the successful production of pilot products, with some samples achieving purity levels of 4N5 and even 4N8. These advancements mark a significant stride toward the domestic industrialization of high-purity quartz sand production.
Academician Mao Jingwen from the Chinese Academy of Engineering emphasized the mineral's exceptional propertiesâheat and corrosion resistance, low thermal expansion, high insulation, and excellent light transmissionâmaking it a strategic and globally scarce resource. As high-purity quartz ore plays an indispensable role in semiconductors and photovoltaics, the discovery is set to energize technological innovation and high-tech competition.
Looking ahead, comprehensive national resource surveys and targeted exploration projects will further clarify the reserves, ensuring a secure supply of this critical material. This pivotal development is expected to stimulate new opportunities in the technology and manufacturing sectors, resonating with innovators and global citizens alike.
