calcium oxide, chemical compound, CaO, a colorless, cubic crystalline or white amorphous substance. It is also called lime, quicklime, or caustic lime, but commercial lime often contains impurities, e.g., silica, iron, alumina, and magnesia. It is prepared by heating calcium carbonate (e.g., limestone) in a special lime kiln to

Mar 19, 2017 Calcium Oxide is a solid with a very high affinity for water it will react with water in the air, or in your skin or anywhere it can and form calcium hydroxide. This reaction is exothermic so it releases a lot of heat while it is reacting there fore as well as being corrosive and causing significant skin irritation,
Formula and structure: Calcium oxide chemical formula is CaO and its molar mass in 56.0774 g mol1. The molecule is formed by the calcium ion Ca+2 and the oxygen anion O2, which form a ionic bond. The calcium oxide ionic lattice is cubic and similar to NaCl lattice, with an ion surrounded by 6 opposite chargeion.
Clumps of calcium oxide formed by reaction with moisture and proteins in the eye are difficult to remove by irrigation. Manual removal by a physician is necessary. NEVER pour water into this substance when dissolving or diluting always add it slowly to the water. Card has been partly updated in October 2005. See sections

Fresh air, rest. Refer for medical attention. Skin, Dry skin. Redness. Skin burns. Burning sensation. Pain.
Crumbles on exposure to moist air. Reacts with water to form corrosive calcium hydroxide, with evolution of much heat. Temperatures as high as 800° C have been reached with addition of water (moisture in air or soil). The heat of this reaction has caused ignition of neighboring quantities of sulfur, gunpowder, wood, and

Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic, alkaline, crystalline solid at room temperature. The broadly used term lime connotes calciumcontaining inorganic materials, in which carbonates, oxides and hydroxides of calcium, silicon,
Calcium oxide definition: a white crystalline base used in the production of calcium hydroxide and bleaching powder Meaning, pronunciation, translations and examples.
Jul 20, 2006 Calcium oxide is affirmed by the FDA as a generally recognized as safe (GRAS) direct food substance (21 CFR 184.1210). Prolonged contact with wet cement, which is alkaline due to the reaction of water with calcium oxide to form calcium hydroxide, can result in fullthickness skin burns that may require
Lime, or calcium oxide, is a principle ingredient in the production of Portland cement, the basis for most mortars and concrete. Hydrated or 'slaked' lime is the chemical calcium hydroxide. This chemical is also used in mortars. Both types of lime are strong bases and are also used in food production (calcium hydroxide is
SigmaAldrich offers Aldrich451711, Calcium oxide for your research needs. Find product specific information including CAS, MSDS, protocols and references.
Use: Calcium Oxide is a highly insoluble thermally stable Calcium source suitable for glass, optic and ceramic appliions. Oxide compounds are not conductive to electricity. However, certain perovskite structured oxides are electronically conductive finding appliion in the hode of solid oxide fuel cells and oxygen
Calcium oxide: Calcium oxide, CaO, also known as lime or more specifically quicklime, is a white or grayish white solid produced in large quantities by roasting calcium carbonate so as to drive off carbon dioxide. At room temperature, CaO will spontaneously absorb carbon dioxide from the atmosphere,
Calcium Oxide (CaO) is cubic crystalline solid (I think it's face centered cubic but need to check on that). It's mainly used in the production of cement. It also produces heat when it's hydrating and forms Calcium Hydroxide (Ca(OH)2). This reaction is actually used in petroleum industry to detect water because Ca(OH)2 is
