Metallic Cesium
产品描述 Product Description
化学符号 Chemicalsymbol: Cs
CAS号 CAs Number:7440-46-2
铯是淡金色稀有碱金属，它的表面可能会因氧化而呈现灰色或黑色,密度约0.96克/立方厘米,熔点为28.44摄氏度沸点为671摄氏度。铯具有高度的活性,非常容易自燃，除了在空气中能够自发燃烧以外，铯在很低温度下就能够与水发生爆炸性的反应,比碱金屈中的其他元素更剧烈。铯可以在汽度低达-116″c的条件下与冰发生反应，由于其高度活性,该金属被分类为危险性物质。
Cesium is a pale gold-colored rare alkali metal, lts surface may appear gray or black due to oxidation. lt has adensity of approximately 0.96 g/cm*, a melting point of 28.44 °c, and a boiling point of 671 °c. Cesium exhibitsextreme reactivity and spontaneously iqnites, Beyond spontaneous combustion in air, it undergoes explosivereactions with water at extremely low temperatures-more violently than any other alkali metal. Cesium reactswith ice at vapor pressures as low as -116°c, Due to its high reactivity, this metal is classified as a hazardoussubstance.
产品质量误差 Product Quality Tolerance
产品质量和技术检验中的误差范围:检验结果的允许误差小于3%。
The permissible deviation in product quality and technical inspection results is less than 3%.
产品批次间的误差 Variation between product batches
由于存在不同的产品批次，每个包装中金属铯的净含量方面存在轻微的差异，误差为0.00555。Due to different product batches, there may be slight variations in the net content of metallic cesium in eachpackage, with an error of 0.00555.
产品的运输 Product Transportation
金属铯和金属铷是碱金属，其化学性质具有反应性，因此必须将产品存放在温度为50°的环境中并进行运输。由于这些产品具有独特的物理和化学特性，因此产品的运输和使用必须由经过认证的专业技术人员按照专业技术和规格标准进行操作。
Cesium and rubidium metals are alkali metals with reactive chemical properties. Therefore, these products mustbe stored and transported at temperatures below 50’c, Due to their unigue physical and chemical characteristicstransportation and usage must be conducted by certified technical personnel in strict accordance withprofessionaltechnical specifications and standards.
用途 Applications
用于金属还原过程，例如制备高纯度金属和还原金属氧化物。
Used in metal reduction processes, such asproducing high-purity metals and reducing metaloxides.
储存方式 Storage Method
纯金属铷通常存储于密封的玻璃安瓿瓶中。
Pure metallic rubidium is usually stored in sealedglass ampoules.
