Tibet quartz discovery boosts China’s self-sufficiency push for hi-tech materials

China has identified a significant new source of high-purity quartz in its western Tibet autonomous region, a development that could bolster the nation's self-sufficiency in critical high-tech materials. The discovery addresses a long-standing reliance on imports, particularly from the United States, for this essential component used in manufacturing solar panels and semiconductors.

This study evaluates Tibet leucogranites as a potential raw material for high-purity quartz.

High-purity quartz is a vital material for numerous advanced technologies, and China currently dominates the global market for many of these finished products. However, domestic access to the raw, high-purity quartz has been limited, necessitating imports. This new geological find in Tibet offers a potential pathway to reshape that dependence.

Our results demonstrate that these leucogranites hold considerable potential to produce high-purity quartz with [silica] contents above 99.995 per cent.

Research published in the European Journal of Mineralogy indicates that leucogranites in Tibet possess considerable potential for producing quartz with silica content exceeding 99.995 percent. This purity level meets or exceeds the stringent requirements for high-tech manufacturing. The authors of the study, from the University of Science and Technology of China and the China Geological Survey, suggest this finding presents a substantial opportunity for China to develop its domestic high-end quartz resources, thereby ensuring a more stable and strategic supply chain.
