- Cobaltous sulfate
Pigment Production
Cobalt(II) sulfate hydrate serves as a precursor in the manufacturing of cobalt-based pigments, such as cobalt blue and cobalt green, which are valued for their vibrant colours and stability in ceramics and glass.
Catalysis
It is utilized as a catalyst or catalyst precursor in various chemical syntheses, including oxidation and hydrodesulfurization processes in the petrochemical industry.
Animal Feed Additive
As an essential trace element, cobalt is vital for ruminant health. Cobalt(II) sulfate hydrate is incorporated into animal feed formulations to prevent and treat cobalt deficiency, ensuring proper vitamin B12 synthesis.
Electroplating
In the electroplating industry, cobalt sulfate solutions are used to deposit cobalt coatings, enhancing the hardness, wear resistance, and appearance of metal components.
Drying Agent
It functions as a drier in paints, varnishes, and inks by catalysing the oxidative polymerisation of drying oils, accelerating the drying process.
