Colloidal Silica under a High-Power Electron Microscope
Colloidal silica under a High-Power Electron Microscope:
1. This electron microscope image clearly reveals the true nanostructure of colloidal silica. The monodisperse silicon dioxide (SiO₂) nanoparticles exhibit highly regular spherical shapes with a uniform particle size distribution.
These nanoparticles are dispersed in the medium in a non-close-packed manner, with clear boundaries between particles, indicating excellent stability of this colloidal silica system and effective prevention of hard agglomeration caused by van der Waals forces.
2. Their smooth surfaces and regular morphology are key to their application as binders for high-precision investment casting, coating additives, and polishing agents for electronic materials.
This image visually confirms the high quality of this colloidal silica product—excellent monodispersity, controllable particle morphology, and superior colloidal stability.
3. Countless nano-sized SiO₂ spheres form the background of this image, which is the physical foundation for colloidal silica's significant application value.
● Uniform Particle Size: The consistent particle size ensures that when used as a catalyst support, it provides evenly distributed active sites; and when used in coatings, it forms a dense yet permeable film.
● Large Specific Surface Area: Each tiny sphere possesses a vast specific surface area, making it excellent in adsorption, surface reactions, and enhancing the mechanical properties of materials.
● Stable Dispersion: The moderate spacing between particles demonstrates the stability of the colloidal system, guaranteeing no sedimentation or gelation during storage and use.
This photo is not just a display of microscopic structure; it is the most direct and powerful proof of its exceptional performance.
