INTRODUCTION. Beryllium (Be) mostly occurs naturally as beryllium aluminium silicate (beryl), 3BeO.Al 2 O 3.6SiO 2.As a naturally occurring element, beryllium is present in rocks, coal and oil, soil and volcanic dust.[] The element forms a light, hard, noncorrosive metal.[] Although beryllium was discovered in 1798, it only became commercially …
The name derives from the Greek word beryllos for "beryl", a gemstone in which it is found (3BeO×Al 2 O 3 ×6SiO 2 ). Beryllium was discovered by the French chemist and pharmacist Nicholas-Louis Vauquelin in beryl and emerald in 1797. The element was first separated in 1828 by the French chemist Antoine-Alexandre-Brutus Bussy and …
Among the mentioned radioisotopes in Table 1, 90 Sr, 137 Cs, 144 Ce, and 147 Pm have shorter half-lives and accompanied by gamma radiation, which would increase the radiation shielding weight. Although 210 Po and 242 Cm have higher power density, their half-lives are shorter. 90 Sr was widely used in the energy transformation batteries …
Beryllium is the fourth element in the periodic table and is a light, brittle, and gray alkaline earth metal. Beryllium is found naturally in coal, rocks, dust, and soil and is typically bonded with other elements.
