WHAT IS CaO POWDER?

It is a white, alkaline crystalline solid at room temperature. It is a very strong caustic chemical compound. CaO is widely known when it’s hydrating and forms Calcium Hydroxide (Ca(OH)2), releasing a large amount of thermal energy.

Calcium Oxide is accomplished by heating calcium carbonate (in limestone or seashells) to above 900 °C, a process called calcination or lime-burning, to liberate a molecule of carbon dioxide (CO2), leaving quicklime.

The quality of CaO powder manufactured by Hao Thinh Co., LTD is strictly control from the mining step to heating to grinding. We choose the purest and highest quality stone quarries which meet our high standard to exploit in Nghe An, Yen Bai. Then, these selective limestones are heated and carefully grinded into nanoparticles to assure the fineness and activity by the modern process.

THE CHEMICAL COMPOSITION OF CaO POWDER

APPLICATIONS OF PURE CAO POWDER

Pure CaO powder is widely used in many industries:

Construction Industry:

Calcium oxide is a key material for the process of making cement thanks to the chemical reaction releasing Ca(OH)2

Glass and metal production

The chemical reaction between calcium oxide and silicate help to produce glass and other metal.

Environmental applications

CaO powder is used to control acidity in soil, as a base it reacts to neutralise the soil to reduce acidity (neutralisation reaction)

Ceramic production

Calcium oxide is a basic material offering attractive possibilities, cost wise, for the ceramic production of a basic refractory.

Other application

CaO powder has many other application such as thermal and plasma spray guns and other coating applications.
