Beryllium is a steel gray and hard metal that is brittle at room temperature and has a close-packed hexagonal crystal structure. It has exceptional stiffness (Young's modulus 287 GPa) and a melting point of 1287 °C. The modulus of elasticity of beryllium is approximately 50% greater than that of steel. The combination of this modulus and a relatively low density results in an unusuall… WebNew x‐ray intensity data from synthetic beryllium oxide crystals have verified the distorted wurtzite‐type structure previously reported by Jeffrey, Parry, and Mozzi. The oxygen z …
