Rhodium silver – what is it?
Silver is a precious metal widely used for making jewelry.
But in its pure form it is almost never used because the product will be too soft.
In order to make it more rigid and suitable for use, are added various metal alloys. For example, if you specify that a piece of jewelry made of silver 925, it means that it is 92,5% silver and 7,5% copper or other similar properties of the metals.
To treat all the silver jewelry needs to be carefully and not to forget the constant care for them. Otherwise, oxidation will occur and silver with the formation of sulphide, which is the black color that will spoil the whole look.
In latest time there are increasingly shiny silver – rhodium plated silver, which is coated with a special solution. It is the Foundation of the metal rhodium (the most brilliant of the group of platinum), which cover the silver with a thickness of 0,1 – 25 microns. Anti-corrosion properties of rhodium is even stronger than platinum.
As a chemical element rhodium is a white metal, similar in external features with silver. He is one of a number of noble metals, rare in nature. Very valuable, are not subject to oxidation, i.e. in air with it with no change.
Practice in jewelry rhodium is most often used as protection against corrosion and oxidation for the production of gold and silver. It is insoluble in alkalis and acids. The jewelry goes well with cubic Zirconia and diamonds. Jewelry with rhodium plating is much better protected from scratches and other mechanical damage, become more solid and the rhodium plated silver has a better Shine than usual.
This method is not too expensive, so widespread. Rediret silver in the following manner: a thin layer of mortar is applied to the product of silver, after which it becomes shiny, not dull and not dark.
Applying a thin layer of rhodium is electroplated elektromekhanicheski method. Thus the rhodium can be jewelry silver jewelry, and utensils (spoons, forks, plates, etc.). Even application of metal onto the surface is achieved by deposition of the ions under the action of electric charge.
