air-slake
Học thuậtThân thiện
Definition
- Verb:
- To alter by exposure to air with conversion at least in part to a carbonate: The process of a material, especially quicklime, undergoing a chemical change when exposed to moist air, resulting in partial or complete conversion to a carbonate or hydroxide.
Usage
- This is a technical term primarily used in chemistry, construction, and industrial contexts. It describes a specific chemical weathering process.
- The verb is typically used in the passive voice or as a transitive verb with a direct object (the material being altered).
Examples
- Verb:
- The pile of quicklime was left to air-slake in the yard.
- To make it safer for handling, they needed to air-slake the lime completely.
- The process will air-slake the calcium oxide, converting it to calcium hydroxide.
Advanced Usage
- Technical Context: The term is almost exclusively used in technical descriptions of material science, historic building restoration, or industrial processes involving lime.
- Traditional mortar recipes often involved using air-slaked lime.
Variants and Related Words
- Slaking (n): The general process of combining a substance with water or, in this specific case, atmospheric moisture.
- Air-slaked (adj): Describes a material that has undergone the air-slaking process.
- We used air-slaked lime for the plaster.
Synonyms
- Weather: In a specific chemical context, to undergo change by exposure to the atmosphere.
- Carbonate: (As a verb) To convert into a carbonate, which is a key part of the air-slaking process for lime.
Notes
- The term is highly specific. The most common and direct usage is in the phrase "air-slake lime," referring to the process where quicklime (calcium oxide) absorbs moisture and carbon dioxide from the air to become calcium hydroxide and eventually calcium carbonate.
