What is Cobalt dinitrate?
Cobalt dinitrate (CAS 10141-05-6), also known as cobalt(II) nitrate, is an inorganic cobalt salt used as a catalyst precursor and micronutrient source.
Where is Cobalt dinitrate used?
- Heterogeneous catalysis: standard precursor for cobalt-based catalysts
- Fischer-Tropsch synthesis and hydroprocessing: decomposes during calcination to yield active cobalt oxide phases
- Fertilizer micronutrient blends: corrects cobalt deficiency
- In soils supporting legume cultivation it improves nitrogen fixation efficiency.
- Ruminant nutrition: cobalt supplementation to support vitamin B12 synthesis
- Petrochemical refining: impregnation agent for supported catalysts
Commercial specifications
- High solubility
- Hexahydrate is the most commercially prevalent grade
