Hebei Rb and Cs Emerging Materials Technology Innovation Center: Leading the New Pattern of High-quality Development in the Rb and Cs Industry Chain
Amidst the thriving global new energy and electronic information industries, Rubidium, cesium, and their compounds, as strategic key materials, have witnessed a rapid growth in market demand, averaging 15% annually.According to the International Energy Agency, in 2022 alone, the global consumption of rubidium salts in perovskite solar cells surpassed 12 tons, while Cesium Atomic clocks achieved a penetration rate of 68% in the time synchronization systems of 5G base stations.
As the sole research and development institution in North China accredited by CNAS for rubidium and cesium materials, our center leverages the key laboratory platform in Hebei Province to establish a comprehensive technology system encompassing "ore purification, material synthesis, and device integration" through systematic technological innovation. Currently, we have developed a demonstration production line capable of producing 50 tons of high-purity Rubidium Chloride and 2 tons of metallic rubidium annually, with technological achievements benefiting 23 new energy and optoelectronic enterprises across the country.
