CAS 7440-48-4 MFCD00010935

化学结构图

SMILES: [Co]

化学属性

Mol. Formula	Co
Mol. Weight	58.93
Boiling Point	2900 °C(lit.)
Density	8.9 g/mL at 25 °C(lit.)
TSCA	Yes
Melting Point	55 ºC
Solubility	134 G/100 ML
Appearance	wire 钴是具有光泽的钢灰色金属，比较硬而脆，有铁磁性，加热到1150℃时磁性消失。钴的化合价为2价和3价。在常温下不和水作用，在潮湿的空气中也很稳定。在空气中加热至300℃以上时氧化生成CoO，在白热时燃烧成Co3O4。氢还原法制成的细金属钴粉在空气中能自燃生成氧化钴。
Stability	对空气敏感
