Rocks that contain silicon, are used for many centuries by people as a building material. Pure silicon, which could be extracted from over a hundred years for the first time in recent decades due to its application possibilities in the microelectronics and the construction of solar cells gained enormous importance. The increased demand from the industry on the one hand and the limited production capacities of the silicon manufacturers on [read more]

French chemist Eugene-Anatole Demarcay is credited with the discovery of europium in 1901 and was named for the continent of Europe. In the 1960s, it was discovered that europium could be used with phosphorous to create a vivid red for color television, allowing revolutionary use of bright colors in new sets. Europium does not occur as a free element in nature, but is found in many minerals. Europium is used [read more]

Also a very important technical resource. Nickel in pure form but used only rarely, but world demand has risen rapidly in steel, and the manufacture of steel is required as a nickel alloy component in large quantities. According to the purpose there are different sorts of nickel alloys identified: eg stainless steel, Nikelin, Monel, nickel silver and constantan. Main producers are Russia, Australia and Canada.

Germanium has been demonstrated for the first time in 1886. It is the element with atomic number 32 in the periodic table and the abbreviation “Ge”. Of course, it occurs as a companion of various ores. It is a semi-metal, the better a semiconductor which has a density anomaly, ie in the liquid state is its poet higher than in the solid. Today it is mainly used in high-frequency technology, [read more]

For the first time in 1803 Rhodium was discovered. It was dissolved in aqua regia, and formed a black lagging. The chemical element Rhodium is a transition metal which is silver-white and hard. It is even tougher than platinum or gold, very elastic and tough. At best it can be processed by hammers. The element is preferably used in catalytic converters and used with nitrogen oxides. The production is very [read more]

The chemist Carl Wilhelm Scheele succeeded in 1778 as the first white molybdenum (VI) oxide to produce. By reducing the oxide with coal, was created in 1782, the of metall molybdenum. Metals counting fossil energy carriers in addition to the winners for commodity investors. Considering the recent price gains, so as flying over molybdenum stands out particularly. With an increase of more than 1000 percent since 1999, which is rather [read more]

Bitcoin is a digital only currency that was created by Satoshi Nakamoto in 2009. The name, Bitcoin, is actually a reference to the software that Nakamoto used to create it, combined with the peer-to-peer network formed from the running of the software. Bitcoin is an online currency only, and is not regulated by the government, or any central bank. While it is not “real” money, it can be used as [read more]

Also a very important technical resource. Chromium in its pure form is rarely used, but world demand has risen rapidly in steel, and in the manufacture of specialty stainless steel is chromium needed as alloy constituent in large quantity.

The rare earth desinate refers to elements of the third group in the periodic table of elements. These elements were first detected in rare minerals, where the name ‘Rare earth’ derives. In technology, these metals have very great importance, because they have unusual properties. You are a variety of high tech applications deployed in and are indispensable. Entire industries could not exist without these metals, and because these metals are [read more]

Almost everyone now owns a mobile phone and find it pleasant when many days without reloading its accessible and you can talk a long time. This is due to the battery which every mobile phone has. In recent years there has constantly developed the technology, modern batteries have become a significant disk space. Most mobile phone batteries use a technology that is based on lithium. Other modern products always use [read more]
