China's Ministry of Natural Resources recently announced that high-purity quartz has been officially identified as the country's 174th mineral type.
High-purity quartz, the newly recognized mineral type, refers to rock that, under current technological and economic conditions, can be processed and purified to produce quartz sand with a silicon dioxide (SiO2) purity of at least 99.995% (4N5) . The impurity levels, inclusions, and particle size must meet the stringent requirements for use in high-tech industries such as semiconductors, photovoltaics, and optics.
High-purity quartz is essential for advanced industries like semiconductors and solar energy. However, global reserves are unevenly distributed, and China relies heavily on imports . Multiple deposits have recently been discovered in provinces such as Henan, Xinjiang, and Anhui . Officially recognizing this new mineral type is a significant step toward localizing resource supply chains for high-purity quartz and safeguarding the security of China's high-tech industrial and supply chains.
