LIME SLAKING 101

In many of these applications, hydrated lime, or calcium hydroxide (Ca(OH) 2), is used. This is produced by adding water to quicklime (calcium oxide, CaO). Initially forming a dry hydrated lime product, the further addition of water creates a hydrated lime slurry in a process known as slaking—the focus of this white paper. Publication Date:
