Overview. The element beryllium is a grey metal that is stronger than steel and lighter than aluminum. Its physical properties of great strength-to-weight, high melting point, excellent thermal stability and conductivity, reflectivity, and transparency to X-rays make it an essential material in the aerospace, telecommunications, information technology, defense, medical, and nuclear
Beryllium is a silvery-white, lustrous, relatively soft metal of group 2 of the periodic table. The metal is unaffected by air or water, even at red heat. When copper and nickel are alloyed with beryllium they not only become much better at conducting electricity and heat, but they display remarkable elasticity.

three reactors has occurred with beryllium in direct contact with the primary coolant water graphite, however, would not be expected to perform adequately in the same environment. As seen in Table 1, the atomic weight of beryllium is significantly less than the other materials.
Learn About the Element Beryllium. A naturally occurring element, Beryllium is the fourth element on the Periodic Table with the symbol Be. Beryllium is one-third lighter than aluminum, yet has six times the specific stiffness of steel. While it is still unknown to many, this amazing metal imparts remarkable physical and performance qualities to its end-use products making
Sep 27, 2021 Chronic beryllium disease primarily affects the lungs. But it may also affect other organs because the blood transports beryllium throughout the body. The mechanism of beryllium disease is not absolutely known. Most likely, once in the body, beryllium combines with certain proteins, causing the release of toxic substances.

Acute beryllium disease is a chemical pneumonitis causing diffuse parenchymal inflammatory infiltrates and nonspecific intra-alveolar edema. Other tissues (eg, skin, conjunctivae) may be affected. Acute beryllium disease is now rare because most industries have reduced exposure levels, but cases were common between 1940 and 1970, and many cases progressed from
