PLATINUM ELECTROPOLISHING
Can you give me a formulation for electropolishing of platinum?
Q. Can you give me a formulation for electropolishing of platinum? V. J.
A. The bottom line answer is no, I cannot give you an easy-to-use formulation. Most precious metals can be electropolished using a melt containing potassium cyanide, or sodium cyanide and a sulfur containing compound such as thiourea. This is a dangerous process and not recommended. Another process uses a melt of potassium chloride at 950°C. This is also not a safe process.
Perhaps a readers can provide some information on how to perform this process.
