China has made a landmark discovery in mineral resource development with the identification of high-purity quartz ore, a material crucial for semiconductors and photovoltaic technologies. Announced by the Ministry of Natural Resources (MNR), the find promises to reshape global supply chains for high-tech industries while addressing China's historical reliance on imported quartz.
The newly classified mineral yields silicon dioxide with purity exceeding 99.995% after processing, meeting exacting standards for advanced electronics and solar panel production. Deposits have been identified across strategic locations including the Qinling Mountains in Henan Province and Xinjiang Uygur Autonomous Region's Altay area through targeted mineral exploration programs.
Domestic enterprises and research institutions have already achieved pilot production capabilities, creating materials graded 4N5 and above – with some samples reaching 4N8 purity. These technological advancements mark a critical step toward establishing China's independent high-purity quartz sand production chain.
'This breakthrough represents more than resource security – it's about strategic positioning in global high-tech competition,' said Chinese Academy of Engineering academician Mao Jingwen. The mineral's unique properties – including exceptional heat resistance, insulation, and light transmission – make it irreplaceable in next-generation electronics and renewable energy infrastructure.
MNR's Huang Xuexiong confirmed plans for nationwide resource surveys to map reserves and prioritize exploration. The initiative aligns with China's broader push to develop 'new quality productive forces' by strengthening domestic innovation capabilities in strategic sectors.
