This chapter deals with characteristics properties, occurrence, refining and production processes, material classes and applications of beryllium. The beryllium content of the earth's surface rocks is estimated to be 4-6 ppm. For conversion to beryllium metal, the beryllium hydroxide is first dissolved in ammonium bifluoride solution and subjected to further purification steps. Application of beryllium in various fields is also briefly described in this chapter. Beryllium powder product characteristics are given. Mechanical properties of beryllium product are given. Properties of beryllium-beryllium oxide composite materials are shown. Coefficient of linear thermal expansion versus temperature for beryllium-beryllium oxide composite is illustrated. Stress-strain curves, tensile strength, yield strength, tensile elongation, Young's modulus, modulus of rigidity versus temperature for hot isostatically pressed beryllium is also illustrated. Ultimate shear strength of beryllium is determined on tear-type specimen. Axial S-N fatigue curves for hot-pressed beryllium block S-200F, notched and smooth, at room temperature is illustrated. Creep strength versus Larson-miller parameter for beryllium is illustrated. Based on animal data, beryllium may cause cancer by inhalation. It is classed as very toxic if inhaled in the form of fine dust or aerosols and can lead to Chronic Beryllium Disease causing seriously impaired lung function in susceptible individuals. Beryllium is also classed as toxic by ingestion and harmful as an irritant to the eyes, respiratory system and skin.
