What does PGE mean in CHEMISTRY
PGE is an acronym for Platinum Group Elements, a group of six metals consisting of platinum, palladium, rhodium, iridium, osmium and ruthenium. These elements are all found in abundance in Earth's crust, although they are usually found together rather than individually. They have similar physical properties and chemical characteristics. They are often referred to as 'precious metals' due to their rarity and economic value. PGEs are used for a wide range of industrial applications including jewelry, automotive catalytic converters, fuel cells, electronics and medical devices.

Shorthand: PGE,
Full Form: Platinum Group Elements
For more information of "Platinum Group Elements", see the section below.
History
PGEs were discovered by early chemists in the 18th century who observed their distinct properties and ability to resist corrosion. By 1840 they had been characterized into six different elements which eventually became known as the PGEs. In recent years advances in technology have allowed for the recovery of these elements from small deposits or residues with greater efficiency making them more commercially available.
Usage
The usage of PGEs varies greatly depending on individual needs but can typically include automotive catalytic converters, fuel cells and electronics such as computer hard drives or TV screens. All have unique electrical properties that make them useful for a variety of purposes ranging from electronic circuit boards to jewelry making. The use of PGEs in medical devices is increasing as well due to their ability to resist corrosion and oxidation which makes them suitable for use within body implants or biomedical tools such as catheters or syringes.
Significance
PGEs play an important role in modern industry owing to their highly conductive electrical properties which make them vital components in many electronics products such as computers, TVs and digital cameras. Their high melting points also mean they can be used at much higher temperatures than other materials making them suitable for a range of applications that require heat resistance such as aerospace engineering or automotive exhaust systems. Furthermore their resistance to oxidation makes them ideal candidates for use within biomedical implants where long-term durability is desired over other materials such as plastic or rubber which may suffer from degradation over time when exposed to certain conditions within the human body e.g..ammonia or sweat exposure.
Essential Questions and Answers on Platinum Group Elements in "SCIENCE»CHEMISTRY"
What is PGES?
PGES stands for Platinum Group Elements, which are a group of precious metal elements that include platinum, palladium, rhodium, ruthenium, osmium and iridium. These elements have unique properties which make them highly sought-after in industrial applications and jewelry making.
Why are PGES important?
PGES are important because they have numerous uses in a variety of industries including automotive manufacturing, medical devices, and electronics. They are also widely used for jewelry production due to their unique properties such as high melting points, resistance to corrosion and tarnishing and strong wear resistance.
How does the automotive industry use PGES?
The automotive industry uses PGES mainly for catalytic converters which reduce the toxic emissions from vehicles by converting more environmental pollutants into safer substances such as nitrogen and oxygen. Additionally, some manufacturers use platinum group elements for auto parts such as spark plugs and other engine components.
How do you mine for PGES?
PGES are mainly mined from lode deposits or from alluvial stream deposits using various techniques including open-pit mining and underground mining. Additionally, they can also be recycled from materials containing these elements such as catalytic converters or jewelry scrap.
How do you refine PGEs?
Refining PGEs involves a complex process which requires specialized equipment such as grinding mills, flotation columns and leaching systems. This process begins with crushing the ore into small pieces followed by a series of chemical processes to separate out the desired elements from impurities.
What currency is PGEs traded in?
PGEs are typically traded in US dollars on commodities exchanges worldwide like the London Bullion Market Association (LBMA). However, certain exchanges may trade them in other currecnies depending on their regulations.
Are there any regulatory considerations when trading PGEs?
Yes, there are many regulatory considerations when trading PGES including restrictions on who can buy or sell them, taxes imposed on traders or brokers involved in transactions related to these metals as well as reporting requirements that must be met by those involved in transactions involving these metals.
Where can I find updated prices for PGEs?
You can usually find current prices for PGEs at websites specializing in precious metals like Kitco or Bloomberg Precious Metals Prices pages alongside other information about their different properties such as purity level and weight measurements etc..
What is the difference between Platinum Group Element ETFs vs physical bullion investing?
An exchange-traded fund (ETF) consists of baskets of stocks backed by actual physical gold bullion whereas physical bullion investing involves actually purchasing real gold coins or bars invested directly into your portfolio without having to purchase individual stocks contained within an ETF. Both allow investors to benefit from fluctuations in market prices but ETF offers more diversification while physical bullion provides greater control over how money is invested
