氯化铯

Our cesium chloride, free-flowing and Redi-Dri™, boasts a purity of ≥99.999% on a trace metals basis. This highly water-soluble crystalline solid is known for its high refractive index and excellent dielectric properties. It is widely utilized in solid oxide fuel cells, lighting devices, solar cells, and nucleic acid separation. While partially soluble in ethanol and methanol. Furthermore, it features a wide band gap of approximately 8.35 eV at 80 K, making it an ideal material for a range of advanced applications. Choose our Cesium Chloride, free-flowing, Redi-Dri(TM), ≥99.999% trace metals basis for optimal results in your applications, leveraging the benefits of unmatched quality and reliability. Low impurities (<10ppm) in cesium chloride (CsCl) significantly enhance its performance by improving charge carrier mobility and optimizing optical properties, leading to higher efficiency in solar cells. In nucleic acid separation, low impurities increase selectivity and binding efficiency, resulting in more accurate isolation and higher yields. Additionally, reduced impurities contribute to greater stability and reliability, ensuring consistent performance and a longer lifespan in both applications.




We packaged Cesium chloride in our innovative Redi Dri(TM) packaging, which easily can prevent the absorption of moisture. The packaging has distinct features and advantages to protect the salts from moisture.

Our cesium chloride, free-flowing and Redi-Dri™, boasts a purity of ≥99.999% on a trace metals basis can be used as
