Palladium derives from the Greek name Pallas, a name associated in Greek mythology with Athena, the goddess of wisdom. Apparently, Wollaston was stimulated to use this name by the asteroid Pallas, one of the brightest of asteroids, which was discovered at about the same time.
Palladium's most incredible ability is that it can absorb up to 900 times its volume of hydrogen, according to the Thomas Jefferson National Accelerator Facility. Because of this ability, palladium is used to store and filter hydrogen.
The current high price of palladium is due to increased demand from China and other countries where the economy is booming. The rise in palladium prices has led to a new trend in the jewelry industry: “palladium plating.” This process involves coating a cheaper metal with a thin layer of palladium.
Palladium has the lowest melting point (2830.82 °F) and is the least dense of the PGMs. Deposits of palladium are rare, but are found in South Africa, Canada, and Russia. Much of the world's demand for palladium is met by recycling catalytic converters.
Gold has many uses and is thought to be the standard for precious metals, trading at $1,654 per ounce. Most investors overlook Palladium, which is even more valuable at $1,954 per ounce, respectively.
In 2021, approximately 200 metric tons of palladium was produced worldwide. Russia had been the leading global producer of palladium in recent years, but ranked second in 2021 next to South Africa. In 2021, South African palladium production was 80 metric tons, while Russian production amounted to 74 metric tons.
"Platinum and Palladium Are 30 Times Rarer Than Gold."
Palladium is regarded as of low toxicity, being poorly adsorbed by the body when ingested. It may cause skin, eye or respiratory tract irritation, may cause skin sensitisation. Liquid may cause burns to skin and eyes. If swallowed, do not induce vomiting, if conscious give water, milk...
Palladium-catalysed reactions are so valuable that, in 2010, their discoverers shared a Nobel prize. But despite its versatility, chemists are trying to move away from palladium. The metal is more expensive than gold, and molecules that contain palladium can also be extremely toxic to humans and wildlife.
Palladium Rarity
Palladium is one of the rarest metals on earth and even more scarce than platinum – 15 times more rare to be precise. If all the platinum in the world fits in your house, then every ounce of palladium can easily squeeze inside your living room.
Rhodium, iridium and ruthenium are perhaps the rarest, roughly 1/5 as common as platinum. However, the sale price of rhodium is typically a bit less than that of platinum, and the rest are even less expensive because they are simply less useful.
Most palladium is used in catalytic converters for cars. It is also used in jewellery and some dental fillings and crowns. White gold is an alloy of gold that has been decolourised by alloying with another metal, sometimes palladium.
Palladium isn't magnetic. If the piece you have is a forgery, it may contain iron. This is because iron is an inexpensive metal that's relatively easy to mold and shape. If your piece contains any amount of iron, it will react to a magnet.
Palladium is 30 times rarer than gold and nearly 15 times rare than platinum. That makes it a unique option for wedding bands and engagement rings. That means it'll be challenging to find a variety of styles and choices at the jewelers because of a low supply.
Two precious metals that are actually more scarce than gold and silver are platinum and palladium. While platinum is currently more well-known, both platinum and palladium are very similar. The differences between the two mainly come down to density and price.
Iron-aluminium compound could replace palladium catalyst, reducing the cost of plastic production. (Phys.org) -- Chemists don't like precious metals – at least not when they need the expensive materials as catalysts to accelerate reactions or guide them in a particular direction.
Palladium is used in emission-reducing catalytic converters in gasoline engines, but the metal's price surge has driven automakers to replace it with platinum.
It is estimated that palladium is still about 15 times rarer than platinum, making it significantly more expensive per ounce. In fact, palladium is currently the most expensive among the four major precious metals (platinum, gold, and silver).
Cadmium is an extremely toxic metal commonly found in industrial workplaces, particularly where any ore is being processed or smelted. Several deaths from acute exposure have occurred among welders who have unsuspectingly welded on cadmium-containing alloys or with silver solders.
It is now cherished for its lustrous silvery-white finish and because of its similar properties to platinum. Palladium is resistant to corrosion and will not tarnish in air.
Protactinium (formerly protoactinium) is a chemical element with the symbol Pa and atomic number 91. It is a dense, silvery-gray actinide metal which readily reacts with oxygen, water vapor and inorganic acids.
1. Rhodium. Rhodium (Rh) is non-radioactive and is the most expensive metal in the world. It is a rare member of the platinum group with a global annual demand of 32 tonnes.
Rhodium is easily one of the most expensive minerals, and if current trends continue to follow the same route they are now, it would not be a surprise to see its prices soar even higher in the future.
