Strategic emerging industries are almost all related to non-metallic minerals and their products. In particular, graphite, fluorspar, pyrophyllite, quartz, these products play an irreplaceable and vital supporting role in new materials. Jet mill pulverization has emerged as a critical enabling technology, providing the necessary precision and purity in particle size reduction to unlock the full potential of quartz, graphite, fluorite, and pyrophyllite in their respective high-tech applications.<\/p>\n\n\n\n

High-purity quartz has excellent physicochemical properties. It primarily serves the quartz glass and integrated circuit industries. Its high-end products find wide application in next-generation information technology, high-end equipment manufacturing, and new materials. Since World War II, manufacturers have used quartz to produce electronic components for communication phones and military radios. Globally recognized high-purity quartz raw materials are essential foundations for today\u2019s high-tech products. They are necessary for a country’s sustainable development of high technology. In Germany, ultra-high-purity quartz materials have been classified as strategic resources, thus limiting their export.<\/p>\n\n\n\n
