Beryllium is a hard, lightweight alkaline earth metal with high stiffness and thermal stability.
Properties of Beryllium | It has high melting point, low density and excellent dimensional stability under thermal stress.
Uses of Beryllium | Used in aerospace structures, precision instruments and X ray equipment where transparency to X rays is needed.
Isotopes of Beryllium | Natural beryllium is mostly Be 9; inhalation of beryllium dust can cause chronic beryllium disease and requires strict occupational controls.
