Magnesium Aluminate Powder / Al2MgO4 Powder (Al2MgO4, 2um, 99.5%)

Magnesium Aluminate Powder

Magnesium aluminate (MgAl₂O₄) is a ceramic compound composed of magnesium oxide (MgO) and aluminum oxide (Al₂O₃). It forms a spinellike crystal structure, making it a versatile and important material with a wide range of industrial applications. Magnesium aluminate is often used in various forms, such as powder, ceramic, or nanomaterials, and has a range of beneficial properties such as high thermal stability, good mechanical properties, high resistance to wear and corrosion, and excellent electrical and optical characteristics.

Applications

Refractory Materials:

Magnesium aluminate is used in refractory materials due to its high thermal stability, resistance to thermal shock, and resistance to slag attack. It is widely used in the manufacture of high-temperature furnaces, kilns, and steel-making linings.

Magnesia-Alumina Spinel Bricks: Magnesium aluminate is often used in bricks and monolithic refractories for applications such as steel production, cement kilns, and glass manufacturing.

Catalysis and Catalysis Support:

Catalyst: Magnesium aluminate nanoparticles are used as catalysts or catalytic supports in chemical reactions such as hydrogenation, dehydrogenation, and cracking. The high surface area of the nanoparticles increases the catalytic activity.

Heterogeneous Catalysis: Magnesium aluminate is an excellent support material for the dispersion of transition metals in heterogeneous catalysis, particularly for reactions requiring high thermal stability.

Optical and Photonic Applications:

Luminescent Devices: Magnesium aluminate is used in the manufacture of phosphors and luminescent devices such as LEDs and laser diodes. The material’s ability to emit light when excited by UV or visible light makes it valuable for lighting and display technologies.

UV-Transparent Substrates: Because magnesium aluminate is transparent to UV light, it is used as a substrate material in UV optics and lasers.

Electronics and Electrical Insulation:

Electrical Insulation: MgAl₂O₄ is used as an electrical insulator in high-voltage equipment due to its high dielectric strength and thermal stability. It is found in insulating components for electric motors, transformers, and switching devices.

Semiconductors: Magnesium aluminate thin films are being researched for use in semiconductor devices due to their insulating properties and ability to be grown on various substrates.

Magnetic Materials:

Spinel Ferrites: Magnesium aluminate is used as a precursor material in the synthesis of magnetic ferrite materials (such as magnesium ferrite – MgFe₂O₄), which are used in electromagnetic shielding, magnetic recording media, and microwave devices.

Bioceramics and Biomedical Applications:

Bone Substitutes: Magnesium aluminate ceramics, especially when combined with other bioactive materials, are being explored as potential candidates for bone substitutes and dental implants. MgAl₂O₄’s biocompatibility and strength make it a suitable material for medical devices that need to withstand mechanical stress.

Drug Delivery: The high surface area of magnesium aluminate nanoparticles can be utilized for drug delivery applications, where the nanoparticles can carry and release drugs in a controlled manner.
