China’s discovery of rare quartz used to make solar panels and semiconductors could help rewrite US import dominance

“Our results demonstrate that these leucogranites hold considerable potential to produce high-purity quartz with [silica] contents above 99.995 per cent,” the team from the University of Science and Technology of China and the China Geological Survey wrote.
The study showed that the high-purity quartz supply exceeded the threshold required for use in hi-tech manufacturing.
The finding “offers a significant opportunity to develop high-end quartz resources in China, ensuring a stable and strategic supply of high-purity quartz raw materials”, the authors said.
