General description
钡是 是一种活泼，柔软带正电的金属，有体心立方晶体 结构。它可以通过真空环境下用铝还原钡的氧化物 制的。它有中等比重和良好的导电性。它 被广泛用于合金，从真空管中去除不需要的气体，及作为 还原剂。
Application
用于合成纯净的 Ba21M2O5HX（M = Ge、SI、Ga、In、Tl）低氧化物 Zintl 相的重要物质。···3
钡可作为前体用于合成Ba3Bi6.67Se13，Ba3Bi6PbSe13，和Ba3Bi6SnSe13
它可在钙钛矿薄膜中作为置换Pd2+的掺杂剂。钡的添加提高了有机-无机卤代铅太阳能电池的能量转换效率。

Oxaliplatin, a platinum-based chemotherapeutic agent, has become a standard treatment for advanced colorectal cancer. The dose-limiting toxicity of this compound is the development of peripheral neuropathy. A tangled panel of symptoms, sensory loss, paresthesia, dysesthesia and pain, may be disabling
