Calcium oxide, commonly known as lime, is a chemical compound with the formula CaO. Hydrated or ‘slaked’ lime is the chemical calcium hydroxide. Calcium Oxide characteristics are: Calcium oxide is usually made by thermal decomposition of materials such as limestone, or shell of shells (or other molluskic shells), containing calcium carbonate (CaCO3, calcite minerals) as lime kilns. Thus, it can be understood that calcium oxide is an ionic compound featuring an ionic bond between calcium and oxygen. The former is important for purifying other compounds and substances such as glucose, … The broadly used term "lime" connotes calcium-containing inorganic materials, in which carbonates, oxides and hydroxides of calcium, silicon, magnesium, aluminium, and iron predominate. CaO reacts with water to form calcium hydroxide. It reacts with and neutralizes acids in the lake formed when nitric and sulfuric acid in acid rain are carried to earth by rain, snow, sleet, and other forms of precipitation. To conclude, Calcium Oxide has other utilities as corrosion protector and neutralization of acids used in the metallurgy industry. Calcium oxide has a medium viscosity and a high surface tension, plus a high to intermediate expansion and contraction rate. CaO has a vast number of industrial uses, as well as in the synthesis of acetylene (CH≡CH), in the extraction of phosphates from wastewater and in the reaction with sulfur dioxide from gaseous waste. Uses of Calcium Oxide. All calcium oxide uses wholesalers & calcium oxide uses manufacturers come from members. It is solid at room temperature. It is a white, caustic, alkaline, crystalline solid at room temperature. This process is called the slaking of lime. CaO (s) + H2O (l) = Ca (OH) 2 (aq) (ΔHr = -63.7 kJ / mol CaO). Hydrated lime is called calcium hydroxide, Ca(OH) 2, which is the cement in concrete. The chemical name of lime is calcium oxide. It is also called as burnt lime. The word lime originates with its earliest use as building mortar and has the sense of sticking or adhering. It is the cheapest alkali available which is an important ingredient in the manufacturing of caustic soda. On emploie l'oxyde de calcium lorsque la présence d'impureté nuit à l'utilisation de la chaux vive. (See Appendix 6.) The chemical name of lime is calcium oxide. If … It is believed that quicklime is one of the oldest chemicals known to the human race. It is mixed with water and sand to form a stiff paste called mortar.
