History of discovery and use of gold, its characteristics<\/h2>\n\n\n\n

The first mentions of applications<\/a> gold dates back 3,000 years before our era. Since ancient times, people's lives and activities have been inseparably connected with this material. It was used to make jewelry and household items, to decorate weapons and works of art. <\/p>\n\n\n\n

\n

The precious element also served as the basis for coinage.<\/p>\n<\/blockquote>\n\n\n\n

\"History<\/span>
The history of gold discovery goes back several thousand years<\/span><\/strong><\/figcaption><\/figure>\n\n\n\n

In the 19th century, the world was shaken by the \"gold rush,\" when precious metal mining<\/a> The scale of the phenomenon had reached unprecedented proportions. Thousands of people traveled to far corners of the world to get Nugget<\/a> material. By the end of the century, large firms had emerged with industrial methods of obtaining pure gold from ores<\/a>. <\/p>\n\n\n\n

\n

According to official data, people have managed to extract more than 161,000 tons of this material throughout history.<\/p>\n<\/blockquote>\n\n\n\n

Top 9 unique ways to use gold<\/h2>\n\n\n\n

In the modern world, the metal is not used to make coins, and the days of the \"gold rush\" are long gone. However, nowadays the material is in demand in industry, the national economy, medicine, chemistry and other industries. Can not do without it, even in the development of space. Let's look at where the use of gold is especially relevant now.<\/p>\n\n\n\n

Widespread use of gold in industry<\/h3>\n\n\n\n

Due to its unique physical properties, the metal is actively used in production. It is not subject to corrosion, has high thermal and electrical conductivity.<\/p>\n\n\n\n

Table: Main industries that use gold.<\/p>\n\n\n\n

Sphere<\/th>Features of Use<\/strong><\/th><\/tr><\/thead>
Defense industry<\/td>The metal is used as a target in reproducing atomic reactions in elementary particle gas pedals. It is used to coat mirrors, which are needed to handle the far reaches of infrared radiation. Gold is also used in the production of the neutron bomb.<\/td><\/tr>
Electronics<\/td>Particles of the precious metal are applied to electrical contacts in microelectronics in the manufacture of microcircuits, connectors, and boards. The element Au has proven to be an excellent material for welding in the production of modern electrical equipment<\/td><\/tr>
Aerospace industry<\/td>In these areas, the material's anti-corrosive properties have proven particularly useful. The metal is used in the process of assembling parts of aircraft engines when sealing contacts. A thin film of gold is used to cover the windows of spacecrafts.  <\/td><\/tr>
Chemical Industry<\/td>The element is actively used as a catalyst for chemical reactions in the production of chemically resistant parts for devices.  <\/td><\/tr>
Transportation industry<\/td>By passing an electric current through the precious element, gold acquires the anti-fog properties necessary for the glass of various vehicles - electric locomotives, seagoing ships, and aircraft.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

The main industrial applications of gold are listed above. However, with the development of science, this material acquires more and more new areas of use. For example, it is being actively introduced in nanotechnology, telecommunications, etc.<\/p>\n\n\n\n

Accelerating chemical reactions<\/h3>\n\n\n\n

Gold has the properties of a catalyst. In other words, it accelerates chemical reactions and optimizes processes. This property has found application in various industries ranging from plastic production to energy production.<\/p>\n\n\n\n

\n

The main advantages of the metal as a catalyst are its long shelf life, reactivity, and high compliance with the desired product. In addition, its nanoparticles are lighter and more efficient than many other catalysts.<\/p>\n<\/blockquote>\n\n\n\n

Using gold in jewelry<\/h3>\n\n\n\n

Since ancient times, people have made from precious material decorations<\/a>It is believed to be the first metal used by man. It is believed to be the first metal used by man. Today, gold is still popular among jewelers: it's hard to imagine a more popular material for jewelry making.<\/p>\n\n\n\n

According to statistics, about 80% of the precious metal mined today is used by jewelers. They make rings, chains, cufflinks, bracelets, pendants, and other items. <\/p>\n\n\n\n

The precious element has a high ductility, it easily takes any shape and does not tarnish, which cannot be said about other metals. <\/p>\n\n\n\n

\n

In addition, the precious element has a pleasant color, luster, it easily changes its hue when mixed with other materials. <\/p>\n<\/blockquote>\n\n\n\n

Gold alloying - a change colors<\/a> and properties - allows jewelers to obtain different types of this metal, for example:<\/p>\n\n\n\n
