Hoe wordt beryllium gewonnen?
How is beryllium made?
Beryllium is most commonly extracted from the mineral beryl, which is either sintered using an extraction agent or melted into a soluble mixture. The sintering process involves mixing beryl with sodium fluorosilicate and soda at 770 °C (1,420 °F) to form sodium fluoroberyllate, aluminium oxide and silicon dioxide.
Is beryllium density?
Beryllium is a metal in group IIA of the periodic table with atomic number 4, an atomic weight of 9.012, and a density of 1.85 Mg/m3. Its melting point is 1277 C and it has a boiling point of 2770 C.
What’s beryllium used for?
Beryllium is used industrially in three forms: as a pure metal, as beryllium oxide, and most commonly, as an alloy with copper, aluminum, magnesium, or nickel. Beryllium oxide (called beryllia) is known for its high heat capacity and is an important component of certain sensitive electronic equipment.
What are 5 uses of beryllium?
Uses and properties
It is relatively soft and has a low density. Beryllium is used in alloys with copper or nickel to make gyroscopes, springs, electrical contacts, spot-welding electrodes and non-sparking tools.
Is beryllium a heavy metal?
Beryllium is a toxic bivalent element, steel gray, strong, light-weight, primarily used as hardening agent in alloys. Beryllium has one of the highest melting points of the light metals.
Is beryllium harmful to humans?
In addition, the International Agency for Research on Cancer (IARC) classifies beryllium as a Group 1 carcinogen (carcinogenic to humans), and the National Toxicology Program (NTP) lists beryllium as a known human carcinogen.
What foods contain beryllium?
Some fruits and vegetables such as garden peas, kidney beans, and pears may have above average levels of beryllium.
What are 3 uses of beryllium?
Uses and properties
It is relatively soft and has a low density. Beryllium is used in alloys with copper or nickel to make gyroscopes, springs, electrical contacts, spot-welding electrodes and non-sparking tools.
What organ does beryllium affect?
Breathing in fumes or dusts of beryllium compounds may injure the lungs. While most commonly associated with diseases of the lungs, beryllium may also affect such organs as the liver, kidneys, heart, nervous system, and the lymphatic system.
What are 3 things beryllium is used for?
End products1 containing beryllium and beryllium compounds are used in many industries including: Aerospace (aircraft braking systems, engines, satellites, space telescope) Automotive (anti- lock brake systems, ignitions) Ceramic manufacturing (rocket covers, semiconductor chips)
What diseases does beryllium cause?
The most common health effects associated with overexposure to beryllium in the workplace include: beryllium sensitization, chronic beryllium disease (CBD), and lung cancer. Beryllium Sensitization — Beryllium sensitization is the activation of the body's immune response to beryllium.
