General Cesium Compound Series Products in China situation

Cesium and rubidium are critical minerals indispensable to the development of strategic emerging industries—such as aerospace, national defense, and information technology—and serve as fundamental raw materials supporting modern high-tech research and development. Cesium does not exist in its elemental form in nature; instead, it is found in trace amounts primarily as salts in terrestrial and marine environments, with scarce global ore reserves.

According to data from the U.S. Geological Survey (USGS), global cesium reserves total less than 200,000 tons, concentrated mainly in Canada, Australia, Zimbabwe, Namibia, and China. Characterized by excellent photoelectric properties and high chemical reactivity, cesium is a premium material for infrared technology applications; it is a vital raw material for national science and technology, the military, and industry, and ranks among my country’s eight key rare metal minerals. Cesium products have a wide range of applications, primarily in fine chemicals, oil and gas drilling, aerospace, optoelectronics, medicine and pharmaceuticals, 5G communications, and fire-retardant materials. Its irreplaceability and superior performance have earned it widespread recognition and large-scale adoption across these sectors.

China still lags behind developed Western nations in the high-end application of cesium; meanwhile, rubidium products are also effectively utilized in high-tech fields such as electronic components, catalysts, specialty glass, and energy.
