卤素的

To restore the ability of chromium can be dissolved in sulfuric acid, hydrochloric acid and High-FE acid and release hydrogen, but also of pure chromium with aqua regia does not work, when there is the presence of halogen ions in the acid can not be long-term stability, high temperature with alkali, hydrogen sulfide, sulfur steam, phosphorus, ammonia, such as carbon monoxide and water vapor reaction of the corresponding compounds, in the high temperature reaction of silicon into the silicide also chromium, chromium alloys with many metals generate a wide range of industrial applications, such as chromium-manganese stainless steel is used extensively for chemical plants.

铬的还原能力强，能溶于硫酸、盐酸和高FE氯酸而放出氢气，但纯铬连王水也不起作用，当有卤素离子存在时，在酸中不能长期稳定，高温时能与强碱、硫化氢、硫蒸汽、磷、氨、一氧化碳和水蒸汽等反应生成对应的化合物，在高温下还能与硅反应成硅化铬，铬能与许多金属生成合金广泛在工业上应用，如铬锰不锈钢大量用于化工设备。
