Why does Nickel Chloride hexahydrate cake easily?

1.Main reason is its strongly hygroscopic and deliquescent . Nickel chloride hexahydrate crystals have a highly polar surface and readily adsorb water vapor from the air;

2. The crystalline structure is prone to instability due to the presence of water molecules. Even slight changes in temperature and humidity can cause the system to become unbalanced, Repeated wet-dry cycles cause the particle contact surfaces to undergo recrystallization and adhesion, resulting in rapid hardening and formation of lumps.

When used in electroplating, under what situation has to use nickel chloride ,not nickel sulphate?

The below three situations :

1. Preventing passivation of nickel anodes (the most critical and essential application scenario)
2. Electroplating of deep holes and complex workpieces
3. Specific coating formulation requirements:Impact nickel (undercoating);High-sulfur nickel, semi-bright nickel;High-chloride nickel plating system

Why is it necessary to have extremely low nitrate levels for nickel chloride hexahydrate in electroplating applications?

The core reason is that nitrate is a strong oxidizing agent, which preferentially reduces at the cathode, severely interfering with nickel ion deposition and damaging the coating quality.
