Palladium Chloride Passivation Test Kit

Available Packing Sizes: 

The reagent keeps colour on good passivated stainless steel. A black spot will appear when the surface has not been passivated correctly. Various qualities of passivation will give graduations of grey shades, ranging from light (acceptable) to dark (unacceptable).

Product Application: 

The RXSOL Passivation Test Kit is an easy and economical test kit to determine the Passiveness of austenitic stainless steel. Stainless steel is protected from corrosion by a thin layer that consists mainly of chromium oxide. Oxygen from the atmosphere is normally able to form and maintain this passive layer. Contamination, surface defects and imperfections disturb the formation and repair of the chromium oxide layer and reduce the resistance to severe or local corrosion. Therefore it is very important to test if your stainless steel is still passive to prevent corrosion and damage.

The measure of passivation of stainless steel can be determined with a palladium chloride reagent. The reagent keeps colour on good passivated stainless steel. A black spot will appear when the surface has not been passivated correctly. Various qualities of passivation will give graduations of grey shades, ranging from light (acceptable) to dark (unacceptable).


Palladium Test
There is no or slight colour change on well passivated stainless steel after 3 minutes wetting with palladium chloride reagent. If after rinsing a gray spot appears, the metal is partially passivated. A black spot will arise when the surface has not been passivated correctly. The palladium chloride reagent is corrosive for stainless steel, therefore it is very important to rinse carefully.

Product Dose: 

Palladium chloride test for active surfaces:

Passive steel does not liberate Hydrogen form Sulphuric acid. Palladium can absorb 900 times its own volume of Hydrogen by Adsorbsion and Occlusion. Hydrogen gas reduces Palladium Chloride PdCl2 easily to form black Palladium metal and Hydrogen Chloride.

H2 + PdCl2 = Pd + 2 HCl

This is the reason that Sulphuric acid or HCl  must be mixed with palladium chloride if the black precipitate of metal must be seen by the naked eye. Passive SS does not liberate hydrogen. Palladium Chloride results can be tested using a mass spectrometer too.

Rinse PdCl2 with DI water from a squirter as the black spot is active.
If free iron ( not oxidised iron ) is present on the SS surface the iron is oxidised by Palladium Chloride ( acid reagent solution ) to iron oxide.

4PdCl2 + 4 H2O + 3 Fe = 4 Pd + 8 HCl + Fe304

Palladium chloride comes in a small bottle with a dropper. The contact time should be 3 min minimum. The shelf life is one year if you keep it in the fridge in a coloured bottle.

we are also  supplying  it. Palladium chloride crystals or deliquiscent powder is soluble in water or alcohol.
