Does beryllium form a crystalline shape
WebBeryllium is a hard metal and steel grey, and it is brittle at room temperature. Its Structure is of a close-packed hexagonal crystal. It has great stiffness and has a melting point of 1287 Celsius. Beryllium’s modulus of elasticity is almost 50% greater than that of steel. It has a fast sound conduction speed of about 12.9 km/s. WebUses. Silicon is one of the most useful elements to mankind. Most is used to make alloys including aluminium-silicon and ferro-silicon (iron-silicon). These are used to make dynamo and transformer plates, engine blocks, cylinder heads and machine tools and to deoxidise steel. Silicon is also used to make silicones.
