The platinum-group metals (PGMs), also known as the platinoids, platinides, platidises, platinum group, platinum metals, platinum family or platinum-group elements (PGEs), are six noble, precious metallic elements clustered together in the periodic table.These elements are all transition metals in the d-block (groups 8, 9, and 10, periods 5 and 6).. …
Ruthenium is a rare, precious metal that falls into the platinum metal category. Its sheen makes it look like platinum, but it doesn't have the exact properties of its metallic cousin. It's rarer and harder than platinum, yet at the same time, it's also more brittle. Ruthenium also contains a high melting point.
converters with palladium. Similarly, manufacturers of electronic parts are also reducing the average palladium content of the conductive pastes used to form the electrodes of multi-layer ceramic capacitors, substituting base metals or silver-palladium pastes which contain significantly less palladium.

Gold Vs Palladium. Palladium stands apart from the rest of the group in terms of pricing, supply, and usage, making it perfect for diversifying your portfolio. Unlike gold and platinum, palladium is relatively affordable yet offers excellent resistance against rust and corrosion. Because it is rarer than gold, though, it can be hard to find ...
Abstract. Ruthenium, rhodium, palladium, and osmium are four of the six platinum group metals (the other two are iridium and platinum). These naturally occurring metals are often found in the environment (e.g., airborne) due to their use in vehicle exhaust catalysts and consequent release in car exhaust from catalytic converters.
Additional metals that are recognized as noble are gold and silver. It is sometimes suggested that rhenium and mercury fit the definition of being a noble metal since they retain anti-corrosive properties like the others. …

EWC Code 16 08 01. European Waste Catalogue (EWC) Code 16 08 01 describes waste that as spent catalysts containing gold, silver, rhenium, rhodium, palladium, iridium or platinum (except 16 08 07) and is classed as a Mirror Non-hazardous code. Some wastes are not automatically hazardous or non-hazardous - they are called mirror entry wastes.

Rhenium $ce{Re}$ reacts slowly at room temperature $ce{->HReO4}$. This will further react with $ce{HCl -> ReCl4 + Cl2}$.$^{[2]}$ ... Platinum, gold and mercury can be dissolved in aqua regia but iridium and silver cannot. Palladium and silver are, however, soluble in nitric acid.
Transition metals make excellent catalysts as they have incompletely filled d-orbitals that allow them to both donate and accept electrons easily from other molecules. Some of the early transition metal catalyzed reactions are still being used today. Despite their long history in catalysis, the discovery of new transition metal catalysts and ...

The most precious metals are rhodium, platinum, gold, ruthenium, iridium, osmium, palladium, rhenium, silver, and indium. Clearly, each of these is rare, and some of them you may not even recognize, so let's look at gold, the de facto mascot of all precious metals. Gold's relative abundance is 0.004 part per million (ppm) in Earth's crust.
These consist of layers of palladium sandwiched between layers of ceramic. Finely divided palladium is a good catalyst and is used for hydrogenation and dehydrogenation reactions. Hydrogen easily diffuses through heated palladium and this provides a way of separating and purifying the gas. Biological role.
