XLogP3:-0.11880
Appearance:Calcium oxide appears as an odorless, white or gray-white solid in the form of hard lumps. A strong irritant to skin, eyes and mucous membranes. Used in insecticides and fertilizers.
Density:3.3-3.4 g/cm3
Melting Point:2572 °C
Boiling Point:2850 °C
Flash Point:2850ºC
Refractive Index:1.83
Water Solubility:Reacts
Storage Conditions:Store at RT.
Vapor Pressure:0 mmHg (approx)
Flammability characteristics:Noncombustible Solid, but will support combustion by liberation of oxygen.
Explosive limit:No explosive propertiy
Odor:Odorless
PH:SATURATED SOLN IN WATER IS ABOUT 12.8
Experimental Properties:Crumbles on exposure to moist air|Commercial grade is usually yellowish or brownish tint, due to iron|Readily absorbs CO2 and H2O from air, becoming air-slaked.|A powerful caustic to living tissue. The powdered oxide may react explosively with water.
Air and Water Reactions: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 straw [Mellor 3: 673 1946-47].
Reactive Group:Bases, Strong
Reactivity Alerts:Water-Reactive
Reactivity Profile:A base and an oxidizing agent. Neutralizes acids with generation of heat. Nonflammable, but will support combustion by liberation of oxygen, especially in the presence of organic materials. Reacts very violently with liquid hydrofluoric acid [Mellor 2, Supp. 1:129 1956]. Reacts extremely violently with phosphorus pentaoxide when reaction is initiated by local heating [Mellor 8 Supp.3:406 1971].
Autoignition Temperature:Not flammable (USCG, 1999)
Flammable Limits:Noncombustible Solid, but will support combustion by liberation of oxygen.
Corrosivity:Corrosive
