What Are the Differences Between Light and Dead-Burned Magnesium Oxide?

Today we’re discussing two different types of magnesium oxide: light and dead-burned. Those may be some odd names, but they are actually the result of how the Dafei Magnesium oxide was made and what it is used for.

An insight into the chemistry of light and dead-burned magnesium oxides

Lets begin with the basics – what is magnesium oxide? White magnesia is a powdery compound consisting of magnesium and oxygen. Due to its resistance to high-temperature and chemical stability, it can be found in industrial processes and products.

Generally, light magnesium oxide is formed by the calcination of magnesium carbonate. This creates a light and fluffy powder that is frequently used in products such as rubber, plastics or ceramics. In contrast, dead-burned magnesium oxide is produced by calcining magnesium carbonate at an even higher temperature. This makes a dense, stable powder widely used in for example in steel production and in environmental applications.

On the differences between light and dead-burned MgO

These differences in producing light and dead-burned magnesium oxide lead to different characteristics and applications. Light magnesium oxide is a highly reactive form of High purity magnesium oxide and is commonly used as a catalyst in chemical reactions. It is also highly appreciated for improving the poor mechanical properties of such materials as plastics and rubbers.

On the other hand, dead burnt mg-oxide is appreciated for its excellent thermal stability and corrosion resistance. That's why it is used in industrial furnaces and kilns. Furthermore, dead-burned magnesium oxide is widely applied for environmental facilities such as waste water treatment and flue gas desulfurization.

The significance of the processing techniques in the production of various magnesium oxide

Its processing will therefore be very important for the final properties and for the possible uses. For example, light pure magnesium oxide is manufactured according to a calcination process, resulting in a fine and reactive powder. It is, therefore, useful in applications where a rapid response is required.

Increasing the temperature or prolonging the heating times, leads to dead-burned magnesia. The claim is that this yields a more stable, less reactive material suited for use where some durability and resistance to harsh conditions are needed.

Taking the thermal stability and reactivity of LMO and DMO into account

The heat stability and reactivity of light and dead burned magnesium oxides are one of the primary distinctions. Calcined light magnesium oxide is very active, and is sometimes used for situations where an extremely fast and powerful chemical reaction is required.

Dead-burned magnesia, on the other hand, is valued for its thermal stability and chemical resistance. This is what makes it an important component in products that will experience high temperatures and harsh environmental conditions without degrading or breaking down.

What kind of magnesium oxide to choose for industrial applications?

When choosing between light burned magnesium oxide and dead burned magnesium oxide for a particular industrial application, factors to take into account should include stability and reactivity, as well as use. The uses of light magnesium oxide are those in conditions which require a rapid and powerful reaction, such as catalysts and chemical additives.
