Green crystals with specific gravity of 1.921, soluble in water and ethanol, deliquescent in moist air.
It is used for electroplating, antiseptic, ammonia absorbent and other chemicals
Store at cool and dry place, prevent from damp and efflorescence.
25kg net, Paper/PE complex bags with double PE inners.
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 :
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.
