On April 10, the Ministry of Natural Resources announced some encouraging news: high-purity quartz ore has officially become China’s 174th recognized mineral species. This seemingly ordinary “stone” is actually the “invisible foundation” for modern technological products such as photovoltaic panels and 5G fibers. Behind this, the research team from the School of Chemical Engineering at Tianjin University, through decades of continuous innovation, has transformed the \"silicon\" element in ores into \"gold\" that supports **high-tech industries**. The “magic” of high-purity quartz lies in its extremely pure silicon dioxide, with a purity of up to 99.995%, meaning that there are only 5 impurities per 100,000 atoms. This material is resistant to high temperatures, has strong insulating properties, and allows light to pass through unobstructed; it is therefore a key raw material for manufacturing high-temperature tubes in photovoltaic panels as well as fiber optic preforms. However, 90% of the world’s high-end, high-purity quartz sand has long relied on mines in countries such as the United States, putting China’s technology industry at risk of being held back. A turning point emerged in the East Qinling Mountains of Henan and Altay in Xinjiang, where Chinese scientists discovered high-purity quartz deposits with quality comparable to those in the United States. However, the discovery of ore is just the first step; the real challenge lies in turning these “rocks” into “ultrapure materials” that can be used in the manufacture of high-tech products. To overcome this challenge, a research team from the School of Chemical Engineering at Tianjin University has spent decades working hard to develop a distillation purification process for chlorosilanes. It functions like a sophisticated \"molecular sieve,\" filtering out impurities in the ore layer by layer to produce polysilicon of extremely high purity. This not only ensures that the product quality reaches international top standards but also reduces energy consumption significantly through multi-tower differential pressure coupling technology, thereby enabling green manufacturing. On this basis, a team from the School of Chemical Engineering at Tianjin University invented an integrated reaction-distillation technology that consolidates the traditional silane preparation process, which requires multiple steps, into a single reaction tower. This one-step process has enabled China to account for over 90% of the world’s silane production, making it the \"technical hub\" for particle silicon manufacturing. As a new generation of photovoltaic material, granular silicon reduces production costs by 30% compared to traditional methods, thereby providing a \"Chinese drive\" for the development of new energy worldwide. These technological advancements enable China’s annual production capacity of semiconductor-grade high-purity quartz sand to exceed 50,000 tons, allowing for gradual self-sufficiency in mid- and low-end products. “Manufacturing materials that used to need to be imported can now be produced using local ores and our own technology ； The pricing power, once monopolized by foreign companies, is beginning to weaken due to the rise of China’s own innovative technologies. ”The head of the R&D team at the School of Chemical Engineering at Tianjin University said, “The value of a ‘rock’ lies not only in its reserves underground, but also in the sweat and wisdom invested in the laboratory.” ”
