Precious metals

Precious metals They are distinguished by very high chemical resistance and practically do not oxidize in air, hence their name. They are also quite refractory.

Precious metals They belong to the group of inert substances that are found in nature in pure form, and not as various compounds or ores.

They are very beautiful in products, highly valued for their intrinsic value, so they are often called as precious metals.

Precious metals have a great economic impact on the global level, so the currency of a state is valued by the gold reserves assigned to it.

Precious metals are held by central banks. The well-being of a country depends on the amount of such reserves, so for many centuries, reserves of these metals have been monitored very carefully. In addition to their financial value, precious metals are widely used in industry due to their physical and chemical properties.

List of precious metals

Classification of precious metals can be performed according to various criteria. In most cases, a distinction is made between base metals such as gold, silver, and platinum, as well as their groups, which include various types and derivatives.list of precious metals includes:

• gold (Au), as well as all 10 types of this metal;
• silver (Ag) has 5 main varieties;
• platinum (Pt), which includes the platinum group metals (ruthenium (Ru), rhodium (Rh), palladium (Pd), osmium (Os), iridium (Ir) and rhenium (Re)) that accompany it in nature.

The pages of this resource use classification of precious metals by groups, which is available in the site map.

Gold and silver are called currency metals. List of precious metals It wasn't always like this. For example, platinum was discovered only in the 16th century by Spanish colonists, and the metal was scientifically described in the 18th century. Palladium, rhodium, iridium, and osmium were discovered only in the 19th century.

Types of precious metals

Unlike currency metals such as gold and silver, there are also types of precious metals, which occupy a worthy place under the name noble metals. Among them:

• platinum (Pt),
• osmium (Os),
• iridium (Ir),
• ruthenium (Ru),
• palladium (Pd),
• rhodium (Rh).

Rhodium is the most valuable metal, and it's significantly more expensive than gold. This silvery metal with a bluish tint was discovered in 1803. Its value is approximately equal to the equivalent in US currency of 1 TP4T230 per gram. Rhodium is very brittle and highly resistant to aggressive environments and high temperatures.

Platinum is the second most valuable element. This chemical element was discovered in 1952. Due to its exceptional chemical stability, platinum is unaffected by any single acid. It does not oxidize in air and does not change color when heated to high temperatures.

Osmium is a rare noble metal, very expensive, the heaviest precious metal, very brittle, and exceptionally hard.

Iridium and ruthenium have almost the same properties - brittleness, increased hardness, and are quite rare.

Palladium is a lightweight, precious metal, more readily available than other platinum group metals. It is ductile, fairly flexible, corrosion-resistant, and fusible.

All types of precious metals have found wide application in some parts of automobile catalysts, neutralizer filters, microelectronics, the nuclear industry, dentistry, chemical and petrochemical production, biomedicine, aerospace instrumentation and the military industry.

Precious metals have become an integral part of every modern person's life. Even if you don't wear jewelry, you still always keep precious metals at hand. How do you understand this? It's very simple! Any modern electronic device (phone, computer, car electronics chips, etc.) contains precious metalsTherefore, even if jewelry itself isn't interesting, it's still worth knowing what white gold, platinum, silver, and other precious metals look like. After all, it would be a shame to waste money throwing away a seemingly useless old part (for example, an old TV lamp—it may contain a fair amount of silver and even gold).

That's why our website contains articles of an introductory nature that don't overwhelm the reader with complex information.

This section contains descriptions and lists of noble metals, their varieties, alloys, physical properties, and chemical characteristics. Separate articles are devoted to descriptions of specific metals and their alloys.

The articles in this section also contain photos and tables with the main technical characteristics of the materials.

We hope the content in the "Precious Metals" section will be useful in solving your problems and questions.
