High-purity Rubidium and Cesium metals are critical strategic elements utilized across quantum technology, aerospace defense, and advanced chemical catalysis.
Rubidium-87 isotope hyper-fine microwave transitions serve as the benchmark frequency standard for satellite navigation (GPS/Galileo), telecom synchronizers, and compact cold-atom quantum gravimeters.
Optical pumping and Bose-Einstein Condensation (BEC) research rely on ultra-pure elemental Rubidium vapor. Ultra-sensitive atomic magnetometers for geological survey and biomedical imaging.
Cesium metal possesses the lowest ionization energy of all stable elements, acting as an exceptional promoter for industrial ethylene oxide synthesis, hydrogenation, and customized specialty catalysts.
Cesium-doped perovskite photovoltaic cell for enhanced thermal stabilityNext-Gen Clean Energy
Perovskite Photovoltaics & Photocathodes
Cesium cation doping dramatically enhances thermal and structural stability in commercial perovskite solar cells while optimizing electron work function in infrared photocathodes and night-vision devices.
Advanced semiconductor patterned wafer featuring microelectronic interconnects and conductive copper metallizationSemiconductor & Nuclear Medicine
Semiconductor Interconnects & Isotope Targets
Ultra-fine 99.9998% copper powder (D50 4.1µm) serves as the core feedstock for advanced semiconductor TSV conductive pastes, high-density sintered interconnects, and cyclotron targets for medical theranostic isotopes (Cu-64 / Cu-67).

FAQ
What packaging volumes and Minimum Order Quantities (MOQ) are supported?
Standard packaging configurations include 100g, 500g, and 1,000g hermetically sealed stainless steel cylinders, as well as 5g to 50g glass ampoules for specialized research. Commercial MOQ starts from 500g, with scalable monthly allocations up to multi-kilogram commercial contracts.
Do you provide batch-specific Certificate of Analysis (COA) and MSDS?
Yes. Every shipment includes an authenticated, batch-numbered ICP-MS Certificate of Analysis indicating exact parts-per-million (ppm) levels for all metallic impurities, alongside a fully compliant GHS Material Safety Data Sheet (MSDS) in English.
How are dangerous goods export controls and international freight handled?
Both Rubidium and Cesium metals are classified under UN Hazard Class 4.3 (Dangerous When Wet). Shipments are coordinated via certified international hazardous cargo forwarders compliant with ICAO/IATA and IMO regulations. Customs import permits and End-User Declarations (EUD) may be requested depending on destination jurisdiction.
