Can China’s caesium-from-brine tech cut reliance on Canadian, Australian ores?
Chinese researchers have developed a novel method to extract caesium from brine, potentially reducing the nation's reliance on imports of this critical strategic resource. The new technique utilizes a sieve-like material that selectively captures caesium ions, overcoming challenges posed by low concentrations and interfering ions in salt lake brines. This breakthrough, published in the Chemical Engineering Journal, could significantly bolster China's domestic supply chain for caesium, which is vital for applications in satellite technology, sensors, and specialized glass.
