Effects of mechanical activation and static pressure treatment on the crystal structure of brucite

Effect of Mechanical Activation on Brucite

Crystal refinement: Through mechanical activation methods such as ball milling, the crystal structure of brucite is destroyed, resulting in grain refinement and increased specific surface area, creating conditions for chemical reactions and improved material performance. Structural distortion: Long-term mechanical force may cause crystal structure distortion and even trigger phase transitions, producing new crystalline phases or amorphous states, thereby changing the physical and chemical properties of brucite. Surface energy enhancement: Mechanical activation increases the surface energy of particles, making the surface rough, enhancing contact and adsorption capabilities with other substances, and has a positive effect on the preparation of composite materials and catalysts. Effect of static pressure treatment on brucite

Structural densification: Static pressure treatment uses high pressure to reduce the distance between brucite crystal lattices to achieve structural densification and increase the density and hardness of the material. Defect repair: Proper hydrostatic treatment helps repair crystal defects and enhance crystal integrity, which is critical for high purity and high crystallinity applications. Phase Transformation: Under extremely high pressure, brucite may undergo phase transitions, such as to magnesium oxide (MgO), involving the reorganization of chemical bonds and fundamental changes in structure. Performance improvement: Static pressure treatment may improve brucite's electrical conductivity, thermal stability, optical properties, etc. Physical and mechanical activation and static pressure treatment are two technologies that change the crystal structure of brucite through physical means. They affect water content through different mechanisms. Physical and chemical properties of magnesite. Mechanical activation increases reactivity by destroying and refining the crystal structure, while hydrostatic treatment improves the integrity and stability of the material by densifying the structure. These two methods provide new possibilities for the application of brucite in fields such as materials science, environmental engineering, and chemical industry, but their specific effects need to be evaluated based on processing conditions and application goals.
