Calcium oxide (99.95%-Ca)

Calcium oxide

Calcium oxide has wide-ranging utility in industry. It is used in making porcelain, cements, mortars, and glass. It is also employed in flue-gas desulfurization in power plants, purifying sugar, drying the solvents/reagents, preparing bleaching powder, calcium carbide, and calcium cyanamide. It also finds use in water softeners, chemical recovery at Kraft pulp mills, biodiesel production, and in petroleum industry for the detection of traces of water. In agriculture it is used to restore the pH of acidic soils (liming). It is useful as a basic catalyst & acid scavenger in several organic transformations, for example, in Arndt-Eistert Synthesis of alpha-diazoketones, synthesis of heterocycles and oximes.This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio.

It is used in cement, glass, steel, paper, chemical and petroleum industries. It acts as a key ingredient in the process of cement making. It is widely used industrially as a dehydrating agent and an absorbent. Further it finds use as a water softener and as a pH regulator for wastewater. It is useful to detect traces of water in hydrocarbons, and in flue-gas desulfurization. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio.

Calcium oxide is a chemical compound that is used in the process of wastewater treatment. It removes phosphorus from sewage by forming insoluble calcium phosphate and prevents the release of phosphate into natural waterways. Calcium oxide also has been shown to remove chromium, nickel, copper, and zinc from wastewater. The removal of these metals may be due to the oxidation of metal hydroxides which are then precipitated by calcium oxides or through the formation of insoluble metal oxides. Calcium oxide can also be used to remove potassium dichromate from water vapor. Calcium oxide is an oxidizing agent that can react with metals at high temperatures and can be used as a catalyst for many reactions. The activity index for calcium oxide ranges between 1-3 and its surface methodology is Langmuir adsorption isotherm.
