  • What is Quicklime and How is it Made? - ScienceStruck

    But the most common treatment is slaking, or addition of water to the quicklime. This is an exothermic reaction, which means it results in the evolution of a large quantity of heat to form calcium hydroxide or slaked lime. The process of hydration is carried out in a continuous hydrator, after which micron-sized slaked lime particles are produced.
