In daily life, many people have heard of quicklime and slaked lime, but they don’t know much about the difference between the two. In fact, quicklime and slaked lime are both lime-based substances, which are different forms of lime. Below, let’s briefly talk about the differences between quicklime and slaked lime from the following aspects:
1. Main component
Quicklime: it is usually a solid block, the main component of it is calcium oxide (CaO), also known as burnt lime.
Slaked lime: it is a powdered solid, the main component of it is calcium hydroxide [Ca(OH)2], also known as slaked lime.
2. Reaction after contact with water
Quicklime: when added to water, it will react violently and make the water boil. This is because quicklime can react with water to form slaked lime, and then release a large amount of heat.
Slaked lime: it does not react violently with water. Its solubility in water decreases with increasing temperature, and the formed calcium hydroxide solution is alkaline.
3. Application
Building material
Quicklime and slaked lime are both common building materials.
- Quicklime can be used to make lime slurry, lime mortar and lime cement, etc.
- While slaked lime can be used to make clinker mortar, clinker mortar, clinker cement, etc.
Agricultural Applications
In the agricultural field, both quicklime and slaked lime are used.
- Quicklime can adjust soil pH and improve soil fertility
- While slaked lime is used for disinfection, insecticide, weed control and crop protection.
Industrial application
- Quicklime is used to make chemicals, such as calcium carbide, soda ash, bleaching powder, etc.
- While slaked lime is used in environmental protection fields, such as sewage treatment and flue gas desulfurization.
To sum up, we can see some differences between quicklime and slaked lime. While, both of them are widely used lime-based substances. At the same time, in practical applications, in order to obtain different particle sizes to meet different application requirements, both need to be ground and graded.
