金属锶

金属锶    Strontium Metal

 

分子式：Sr                                                                                                     分子量：87.62
物化性质：银白色柔软金属。相对密度2.63，熔点7690C，沸点13840C。活泼性强，在空气中迅速被氧化，表面形成黄色氧化膜。在空气中粉碎时刻自燃。遇水即分解释放出氢及大量热，使氢引起燃烧，发出深红色火焰。溶于酸类并产生氢气引起燃烧，溶于醇。

规格指标

 

用途：用于铸造铝合金的变质剂和镁合金的细化剂，炼钢工业的优良脱氧剂、脱硫脱磷剂、难熔金属的还原剂，是提高薄壁铸铁件力学性能的优良添加剂；在电真空技术中，被用作高效吸气剂。
