• High-Purity Magnesium Oxide Powder: For advanced ceramics, electronic materials, and laboratory research requiring controlled impurity levels.

• Light-Burned Magnesium Oxide: Generally more reactive and commonly used in chemical processing and selected industrial formulations.

• Hard-Burned Magnesium Oxide: Lower-reactivity material for selected industrial and refractory applications.

• Dead-Burned Magnesium Oxide: Used in refractory products requiring high-temperature stability and low reactivity.

• Fine and Micronized MgO Powder: For applications requiring controlled particle size or fine ceramic processing.

1. What is magnesium oxide powder used for?

Magnesium oxide powder is used in refractory bricks, advanced ceramics, electrical insulation, construction materials, industrial processing, and laboratory research.

2. What is the chemical formula of magnesium oxide?

The chemical formula is MgO, consisting of magnesium and oxygen.

3. What purity levels are available for magnesium oxide powder?

Purity depends on the grade and application. Industrial grades and high-purity grades may be available, including material specified at 99.9% or higher. Confirm impurity limits with the supplier.

4. What is the difference between light-burned and dead-burned magnesium oxide?

Light-burned MgO is generally more reactive due to its processing conditions and surface characteristics. Dead-burned MgO is processed at higher temperatures to reduce reactivity and is commonly used in refractory applications.

5. Is magnesium oxide powder suitable for high-temperature applications?

Yes. MgO has a melting point of approximately 2,852°C and is widely used in refractory and high-temperature ceramic applications. Actual operating limits depend on the grade, atmosphere, and surrounding materials.

6. Can REG Metals source custom magnesium oxide powder?

REG Metals can assist with sourcing MgO powder to requested purity, particle size, reactivity, grade, and packaging specifications, subject to supplier availability.
