Advantages of Spherical Magnesium Oxide
High surface area: The spherical shape provides a higher surface area for enhanced interaction with the surrounding medium.
Low Zeta Potential: The negative charge allows spherical magnesium oxide to be dispersed in water and other solvents.
Excellent flowability: The spherical form helps to improve the flowability of the powder for easy handling and dispersion.
High thermal stability: Its high melting point and oxidative stability make it suitable for high temperature applications.
Low hygroscopicity: Its low hygroscopicity allows it to maintain its performance in humid environments.
