Researchers from Tianjin University have managed to extract high-purity quartz from ore. High-purity quartz are rocks that can be processed and purified to get silicon dioxide with a minimum purity of 99.995 percent. With high temperature resistance and good insulation, the material is crucial to the manufacture of photovoltaic panels and 5G optical fiber.
