Differences between Hydrated lime and quicklime | Sodimate

The main differences between hydrated lime and quicklime are their reactivity & their chemical composition. Hydrated lime and quicklime are both calcium compounds. In its hydrated state, calcium is called calcium hydroxide, and in its pure state it is called calcium oxide, or quicklime.. Calcium oxide has a heavy density (65lb/ft³) and is more reactive than hydrated lime.

Quicklime, (in pellet form), must first be slaked, or mixed with water then heated to turn it into hydrated lime before use. When quicklime is mixed with water there is a potential for explosions due to the heat released from the chemical combinations. Lime also has reactions with alum and ferric sulfates so direct mixing should be avoided.
