What are the uses and properties of beryllium?
What are the uses and properties of beryllium?
Beryllium is a silvery-white metal. 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. Mixing beryllium with these metals increases their electrical and thermal conductivity.
What is beryllium element used for?
Beryllium is used as an alloying agent in producing beryllium copper, which is extensively used for springs, electrical contacts, spot-welding electrodes, and non-sparking tools. It is applied as a structural material for high-speed aircraft, missiles, spacecraft, and communication satellites.

How is neodymium used?
The most important use for neodymium is in an alloy with iron and boron to make very strong permanent magnets. This discovery, in 1983, made it possible to miniaturise many electronic devices, including mobile phones, microphones, loudspeakers and electronic musical instruments.

What is an interesting fact about beryllium?
Interesting Beryllium Facts: Though Beryllium is a relatively soft metal, it is actually hard and at room temperature, it is a brittle element. Of all alkaline earth metals known to us, Beryllium is the lightest of all.
What are 3 uses of neodymium?
Uses of Neodymium Neodymium is used with iron and boron to create powerful permanent magnets, also called NIB magnets. NIB magnets are used in computers, cell phones, medical equipment, toys, motors, wind turbines and audio systems. Neodymium is used as a crystal (neodymium-doped yttrium aluminum garnet) in lasers.
Who is the largest producer of neodymium?
The world’s production of neodymium was about 7,000 tonnes in 2004. The bulk of current production is from China. Historically, the Chinese government imposed strategic material controls on the element, causing large fluctuations in prices.
What are 3 uses for neodymium?
Does the human body use beryllium?
Most likely, once in the body, beryllium combines with certain proteins, causing the release of toxic substances. These are responsible for the lesions seen in the lungs. Certain cells form masses of tissue called granulomas in response to beryllium.
What elements does beryllium react with?
Chemical properties Beryllium reacts with acids and with water to form hydrogen gas. It reacts briefly with oxygen in the air to form beryllium oxide (BeO). The beryllium oxide forms a thin skin on the surface of the metal that prevents the metal from reacting further with oxygen.
How is beryllium used in other nuclear applications?
Other nuclear applications also utilize beryllium. Beryllium, given its unique atomic, physical, and chemical characteristics, is widely used as a “window” for x-rays and gamma rays. Beryllium, intimately mixed with high-energy alpha radiation emitters has been successfully used to produce neutron sources.
What are the properties of the element beryllium?
What is Beryllium? 1 Beryllium is an element with an atomic number of 4 in the periodic table. 2 It is a bivalent and highly toxic element. 3 The element has one of the highest melting points among the light metals. 4 Beryllium exists in 30 different minerals, among which bertrandite, beryl, chrysoberyl, and phenacite are the most… More

What are the chemical properties of neodimium metal?
Neodimium is a lustrous silvery-yellow metal. It is very reactive and qickly turnishes in air and the coated formed does not protect the metal from further oxidation, so it must be stored away from contact with air. It reacts slowly with cold water and rapidly with hot. Applications.
