Wie entsteht Beryllium?
Herstellung. Elementares Beryllium lässt sich durch Reduktion von Berylliumfluorid mit Magnesium bei 900 °C herstellen. Die Weltjahresproduktion an Beryllium-Metall betrug 2004 ca. 100 t.
Welche Eigenschaften hat Beryllium?
Weitere Eigenschaften Beryllium ist ein Leichtmetall mit mäßiger elektrischer Leitfähigkeit. Das Metall ist sehr spröde. Die Oberfläche hat einen silbrigen Glanz. Beryllium (auch seine Verbindungen) ist ein starkes Gift, wirkt krebserregend (cancerogen) und als Mutagen auf das Erbgut.

How much beryllium is in the environment?
Beryllium in the environment. The beryllium content on Earth crust is 2.6 ppm, in soil 6 ppm. Beryllium in soil can pass into the plants grown on it, provided it in a soluble form. Typical levels in plants vary between 1 and 40 ppb, too low to affect animals which eat these plants.
Does beryllium dissolve in water?
Beryllium as a chemical element occurs naturally in soils in small amounts, but human activities have also increased these beryllium levels. Beryllium is not likely to move deeper into the soil and dissolve within. groundwater. In water, chemicals will react with beryllium, causing it to become insoluble.
What is the scientific name for beryllium?
Others preferred the name beryllium, based on the gemstone, and this is now the official name. Beryllium metal was isolated in 1828 by Friedrich Wöhler at Berlin and independently by Antoine-Alexandere-Brutus Bussy at Paris, both of whom extracted it from beryllium chloride (BeCl 2) by reacting this with potassium.
What is beryllium and what are its side effects?
Beryllium can also cause allergic reactions with people that are hypersensitive to this chemical. These reactions can be very heavy and they can even cause a person to be seriously ill, a condition known as Chronic Beryllium Disease (CBD). The symptoms are weakness, tiredness and breathing problems.
