Description
Magnesium Oxide (MgO) Micron Powder, Purity: 99.5+ %, Size: -325 mesh
Product Description:
Magnesium Oxide (MgO) Micron Powder with 99.5+% purity and -325 mesh particle size is a high-performance refractory and functional material widely used across various advanced applications. This white, fine powder is known for its high thermal stability, strong basicity, and excellent electrical insulation properties. With a specific surface area of 10 m²/g (BET), it offers excellent reactivity and dispersion in composite systems.
MgO exhibits a high melting point, low electrical conductivity, and superior corrosion resistance, making it ideal for refractory materials, ceramics, glass, catalyst supports, and electrical insulation. Its fine micronized form improves sinterability, uniformity, and integration into complex matrices.
The product’s chemical profile reflects extremely low levels of impurities like CaO, Cl, Fe₂O₃, SiO₂, Al₂O₃, and B, ensuring optimal performance even in sensitive electronic, optical, or high-purity industrial applications.
