Abstract: High purity quartz (HPQ), as an indispensable key basic material, has been widely used in strategic emerging industries including the new-generation information industry, new energy, new materials, etc., due to its superior physicochemical properties. However, HPQ resources are scarce and concentrated in countries such as the United States, Norway, Russia, and India. In China, 4N5 grade HPQ (SiO₂ content ≥99.995%) is primarily dependent on imports. At present, the domestic production capacity of high grade HPQ is limited and the demand exceeds the supply. In the future, it is expected that China's demand for 4N grade HPQ (SiO₂ content >99.99%) will grow rapidly to 380 000 t by 2025 with the rapid expansion of demand in the photovoltaic and semiconductor industries. As a result, the supply security of HPQ resources will be prominent. The current situation of global HPQ resources, current market supply and demand, major producers as well as consumption trends were comprehensively analysed. Furthermore, the countermeasures were proposed, including HPQ minerals as strategic minerals, strengthening strategic and scientific research on HPQ, and establishing a whole-chain evaluation system, based on the current situation of China's HPQ industry. These would be of great value in ensuring the security of HPQ supply in China.
