Methods of Production and Applications of Bohrium
Methods of Production of Bohrium:
Bohrium (Bh), being a synthetic element, is not found naturally on Earth. It can only be produced through nuclear reactions in a laboratory setting. The primary method used for the production of Bohrium is through nuclear fusion reactions involving heavy-ion bombardment. Some common methods employed in the synthesis of Bohrium include:
Cold Fusion: In cold fusion reactions, a heavy-ion beam is accelerated and directed towards a target composed of a heavy element, such as lead or bismuth. The aim is to induce a fusion reaction between the projectile and the target nucleus, resulting in the formation of a compound nucleus that undergoes radioactive decay, eventually leading to the creation of Bohrium isotopes.
Hot Fusion: Hot fusion reactions involve the use of even heavier projectiles, such as calcium or titanium, which are accelerated and collided with a target material containing a heavier element. The high energy of the collision enables the formation of a compound nucleus, which subsequently undergoes radioactive decay, leading to the production of Bohrium isotopes.
