| 密度 | 9.8 g/mL at 25 °C(lit.) |
|---|---|
| 沸点 | 1560 °C(lit.) |
| 熔点 | 271 °C(lit.) |
| 分子式 | Bi |
| 分子量 | 208.98000 |
| 精确质量 | 208.98000 |
| 外观性状 | 银色-灰色或微红的金属,或黑色粉末 |
| 蒸汽压 | <0.1 mm Hg ( 20 °C) |
| 储存条件 | 应贮存在阴凉、通风、干燥、清洁的库房内。 |
| 稳定性 | 在常温下稳定，加热则呈淡蓝色火焰而燃烧，并生成黄色或褐色氧化铋。熔融的金属经凝结后体积增大。避免与氧化物、卤素、酸、卤间化合物接触。
在没有空气存在时不溶于盐酸，通入空气可缓慢地发生溶解。由液态到固态时体积增大，膨胀率为 3.3％。质脆易粉碎，导电导热性差。加热时能与溴、碘反应。室温下，铋不与氧气或水反应，加热到熔点以上时能燃烧生成三氧化二铋。铋的硒化物和碲化物具有半导体性质。 |
