Palladium is the most common of the platinum group metals (PGM). It is the only member of PGM that is dissolved in nitric acid by itself. It is a steel white metal with a melting point of 1554.9 °C (2830.82 °F). Just like silver, molten palladium can dissolve several times it's volume of oxygen so care should be taken when melting palladium.
The preferred salt is usually Sodium Nitrate. The chemistry behind AR is a bit more involved then you might expect, so we will just go over what is necessary for us to understand the process, in simple terms. In Aqua Regia, the Nitrate ions serves as an oxidizer where the Chloride ions act as sort of "receptors" and accommodate the oxidized metals.
Feb 27, 2016· The flux is a mixture of several reagent chemical such as borax, silica, sodium nitrate, sodium carbonate and fluorspar. Borax is a white crystalline mineral used in glass and ceramic enamel mixes. In the smelting process, borax helps to reduce the gold smelting point of the charge and capture metallic oxides. The addition of this reagent must ...
Sulfuric acid (also spelled sulphuric acid or in old texts as oil of vil) is one of the strong mineral acids and has a number of practical uses in refining.The acid differs from hydrocloric acid and nitric acid in that it contains two hydrogen atoms that can be ionized in water. This means that concentrated sulfuric acid and diluted can appear as two different acids.
