Characteristic
Cobalt sulfide is the name for chemical compounds with a formula CoxSy. Well-characterized species include minerals with the formula CoS, CoS2, Co3S4, and Co9S8. In general, the sulfides of cobalt are black, semiconducting, insoluble in water
Chemical formula:CoxSy
Molar mass:90.9982 g/mol
Appearance:black solid (alpha)
grayish-red crystals (beta)
Density:5.45 g/cm3
Melting point:1195 °C
Solubility in water:0.00038 g/100 mL (18 °C)
Solubility:slightly soluble in acid
Magnetic susceptibility (χ):+225.0·10−6 cm3/mol
Crystal structure:octahedral (beta)
Application
In combination with molybdenum, the sulfides of cobalt are used as catalysts for the industrial process called hydrodesulfurization, which is implemented on a large scale in refineries. Synthetic cobalt sulfides are widely investigated as electrocatalysts.
