Nickel sulfate

Nickel sulfate (CAS 7786-81-4), also sold as NiSO4, is an inorganic nickel salt primarily used as an electrolyte source in industrial electroplating and surface finishing operations.

Where is Nickel sulfate used?

• Electroplating: standard nickel source for decorative and functional coatings on automotive parts, electronics connectors, and hardware
• Catalyst manufacturing: precursor
• Battery production: key precursor in synthesizing nickel-rich cathode materials for lithium-ion cells, particularly NMC and NCA chemistries
• Textile and leather processing: mordant to fix dyes onto fiber substrates, improving color fastness in finished goods
• Mining: nickel sulfate solutions in hydrometallurgical refining to recover and purify nickel from ore concentrates
• It delivers controlled nickel deposition onto metal substrates.

Good to know: Deposit quality and bath stability depend on consistent nickel ion concentration during the process.

Commercial specifications

• Purity levels typically range from 98% to 99.5% depending on the specific industrial requirement.
• Bulk quantities in bags or drums, with high-purity battery-grade material increasingly offered to meet EV supply chain requirements.
