| Overview | Rubidium (Rb) and cesium (Cs) were discovered in 1860 and 1861. Due to the scarcity of rubidium and cesium resources, it is expensive and has not been known for a long time, and has restricted people's research on its properties, so it has not been used in industry for more than half a century. Only in 1920 did people gradually use rubidium hooks to make photocell. Before the First World War, only Germany produced a small amount of rubidium cesium. During the Second World War, cesium was used as a photosensitive material, and the amount increased, but it was still limited in application due to economy and scarcity. In 1957, the United States successfully developed a process for extracting rubidium and cesium with mixed carbonate lye, which made a historic breakthrough in the production of rubidium and cesium. Since the 1960s, rubidium cesium and its compounds have been widely used in the electronics industry, optical instruments, glass ceramics, petrochemicals, medicine, national defense and military industry, nuclear energy and other fields. |
