What is Nickel sulfate hexahydrate?

Nickel sulfate hexahydrate (CAS 10101-97-0) is the primary nickel salt used in electroplating and surface finishing operations.

Electroplating: core electrolyte component in Watts baths and sulfamate-based systems for connectors, automotive parts and consumer hardware
Plating baths: soluble nickel ions enabling controlled deposition onto metal substrates
Battery cathode precursors: nickel feedstock for NCM and NCA active materials
Catalyst production: precursor for hydrogenation catalysts used in edible oil processing and petrochemical refining
Agricultural micronutrients: corrects nickel deficiency in crops, particularly legumes
It functions as the foundational nickel source in electronics, metalworking and battery material process chemistry.

Purity typically 98% to 99.5%+
Battery-grade material subject to tighter specifications on trace metal impurities
