It is also used in research, from quantum computing to ultra-cold atom physics, and in specialty glass and photoelectric cells. ### Other uses - Rubidium-82 for cardiac PET imaging - Specialty glass and fibre optics - Catalysts - Photocells and vapour cells for sensors ## Rubidium supply and demand factors Rubidium is a by-product of cesium and lithium mining from a few pegmatite deposits, and its market is small and illiquid. Demand from atomic clocks, research and specialty glass is steady, and prices are negotiated privately between a handful of suppliers and buyers. ### What moves the price - Output from the few cesium and lithium pegmatites - Atomic clock and quantum research demand - Specialty glass and photocell demand - Supplier pricing ## Rubidium price history Rubidium has a tiny market, supplied by a few producers to a few buyers, and its price rarely changes. As of October 2026, the Stockatomics benchmark price is $24,530 per kg contained. ## Where rubidium is produced Rubidium is a by-product of cesium and lithium mining from a few pegmatite deposits, notably in **Canada** and Africa, and production data are scarce. **China** is believed to be the main producer of rubidium compounds. ## Why rubidium is a critical mineral Rubidium is on the **US critical minerals list**. Volumes are tiny, deposits are few, and timing and research uses have no ready substitute. ## How the rubidium benchmark price is calculated Stockatomics publishes a US benchmark price for rubidium in US dollars per kg contained, reading as of October 2026. The price is for rubidium metal. The market is tiny, so the price moves less often than those of exchange-traded metals. ## FAQ ### What is the price of rubidium per kg today?
