-----Need very small quantity of Palladium plating solution
Q. Hi, I am a senior at UC doing work with Pd-MOS and wanted to know where I can find small, less expensive solutions of palladium for electroplating? My budget is limited, but so is the amount of solution I need, if there is any company that sells smaller amounts, I would very much appreciate this!
Thanks,

A. Try sciencelab.com website. 1 gr palladium chloride cost around 130 USD. Cheapest and simplest is to make your own palladium chloride -- dissolve some palladium in aqua regia and then evaporate it slowly. And one very basic and simple palladium plating solution formula(deposits obtained from this solution are bright,white and dense):
0,5 gr palladium(as chloride)
60 gm sodium hydroxide
1 lit water
pH 10-14
According to J.Fischer, D.Weimer:

A. If you don't feel comfortable in making up your own solution, you may choose to purchase the solution ready to use in a one liter bottle. Most ISO 9002 registered suppliers have quality control measures to ensure good product going out the door. You could do a Thomas Register search for "precious metal suppliers". Keep in mind some companies have a dollar minimum per order. I haven't checked the price of Pd lately, but I can't see it being 130 USD per gram. Buying one gram of Pd won't yield much plating thickness as most solutions run Pd @ 8-10 grams per US Gal. If you want to bottle up the solution for future use you can do so, it will contain sufficient metal to do additional plating. Good Luck!

A. You may also approach brush plating houses. They are used to selling small quantities of chemicals and most offer a palladium solution (some advertise here).

Q. In the solution formula, is that 5 grams of palladium chloride or a half a gram?

A. Hi Steve. I can't verify whether Goran's formula works, but I can verify that "0,5" is a European way of expressing our "0.5" :-)
