What is Lithium molybdate?
Lithium molybdate (CAS 13568-40-6) is an inorganic salt used industrially as a corrosion inhibitor, protecting metal surfaces in aqueous and high-temperature environments.
Where is Lithium molybdate used?
- Water treatment: dosed into closed-loop cooling and heating circuits
- Metalworking and lubricants: cutting fluids, grease and lubricant formulations
- Coatings and surface treatment: non-chromate corrosion inhibitor alternatives
- It forms a passive protective layer on metal substrates, reducing oxidative degradation.
Good to know: Molybdate-based inhibition offers performance at elevated temperatures. Non-chromate alternatives support compliance with restrictions on hexavalent chromium compounds.
Commercial specifications
- Technical and high-purity grades
- Multi-kilogram bags or drums
- Bulk quantities for large-scale procurement
