Beryllium is a chemical element that is light and silver in color. It is useful for various applications in its alloyed, oxide, and metallic forms. Beryllium hydroxide, Be (OH) 2, an oxide of beryllium, is an amphoteric hydroxide, which dissolves in both acids and alkalis. It is very light in weight and has melting points as high as 1,280C, which is the highest of all light metals. It has excellent physical properties such as high stiffness, resistance to corrosion from acids, and high electrical & thermal conductivity.
