Calcium oxide; unslacked lime; -- so called because when wet it develops great heat. See 4th Lime, 2.
A material that is mostly calcium oxide (CaO) or calcium oxide in natural association with a lesser amount of magnesium oxide. Quicklime is capable of combining with water to form hydrated lime.
A common name for calcium oxide, a fast-acting product added to the soil for decreasing acidity and to provide calcium as a plant nutrient.
CaO, calcium oxide, a caustic material made from limestone which has been burned to drive off the carbon dioxide, remains very unstable until slaked.
also called lump lime, caustic lime, or unslaked lime. This was the name given the lime (CaO) as it was removed from the kilns and packed into barrels. It was "quick" to stick to the skin. Handling the product is hazardous, as it is caustic, takes water from the flesh, and gives off heat. This heat is enough to char wood, and warehouses and schooners shipping lime were known to catch fire.
Another term for lime, or calcium oxide (CaO), used in many water and wastewater treatment operations such as softening, coagulation, and phosphorus removal.
An alkali chemical also known as calcium oxide or caustic lime. A colorless or white powder which burns human skin on contact. Several inches of this powder were placed in the bottom of cattle cars prior to loading in Jews and other victims of Nazi roundups.
a white crystalline oxide used in the production of calcium hydroxide
Calcium oxide which is a crushed limestone that has been calcined.
It is a calcium oxide that is crushed limestone and has been calcined.
A calcium oxide material produced by calcining limestone to liberate carbon dioxide, also called “calcined lime” or “pebble lime”, commonly used for pH adjustment. Chemical formula is CaO.
The first solid product CaO that is obtained by calcining limestone and that develops great heat and becomes crumbly when treated with water; lime; before it can be used in construction, quicklime must be slaked in water and aged for at least 2 weeks.
A form of calcium oxide that dissolves rapidly in water to form a hydroxide with the liberation of heat. Used in fertilizer manufacture and amelioration of acid soils.
