Calcium Oxide Production

Calcium oxide, characteristics, properties and production

Obtaining calcium oxide: Calcium oxide is obtained by the following chemical reactions: 1. by thermal decomposition of limestone: Са2СО3 → Cao + CO2 (t = 900-1200 oC). It is an industrial method of producing calcium oxide. Technologically, the process industry carry out in special shaft furnaces. 2. by burning calcium in air:

Calcium oxide CALCINOR

Calcium oxide and the specific products derived from it are obtained by the process of calcination of calcium carbonate at high temperature. CaCO 3 + Heat → CaO + CO 2. Calcium oxide is an alkaline product that allows the regulation of many industrial processes. Its principal properties depend on its chemical composition and the thermal treatment that the mineral has been subjected to, which

DE19614430C1 Production of calcium oxide from

Production of CaO from precipitated CaCO3 containing (in)organic components comprises heating to above 900 deg C, at which the CaCO3 decomposes into CaO and CO2, and adding sufficient amounts of O2 to combust the organic components. The novelty is that the CaCO3 is initially dried and the dried powder fed to the combustion chamber of a pulsation reactor, where it is mixed with combustion air

Calcium oxide Wikipedia

Calcium oxide is usually made by the thermal decomposition of materials, such as limestone or seashells, that contain calcium carbonate (CaCO 3; mineral calcite) in a lime kiln. This is accomplished by heating the material to above 825 °C (1,517 °F), [6] a process called calcination or lime-burning,to liberate a molecule of carbon dioxide (CO 2 ), leaving quicklime.

Role of calcium signaling in the activation of

By plotting the difference between the rates of oxygen consumption in State 3 with L-Arg and with NMMA at various calcium concentrations, a K(0.5) of 1.2 microM intramitochondrial free calcium was obtained, similar to the K(0.5) (0.9 microM) of the dependence of the rate of nitric oxide production on calcium concentrations. The activation of dehydrogenases, followed by the activation of mtNOS, would lead to
