Alumina Dispersion
Industries such as lithium battery separators, thermal interface materials (TIMs), electronic ceramic slurries, polishing fluids, and high-performance coatings demand exceptional dispersibility. Due to their large specific surface area and high surface energy, nano-alumina powders tend to agglomerate easily, forming large secondary particles that compromise performance. Effective dispersion requires each nanoparticle to be individually surrounded by solvent molecules, often aided by dispersants or surface treatments that provide electrostatic repulsion or steric stabilization. KOSNANO’s pre-dispersed nano-alumina solutions eliminate the need for secondary dispersion—they can be directly incorporated into paints, slurries, and coating systems, significantly enhancing process efficiency and consistency.
Your Trusted Expert in Alumina Dispersion
KOSNANO provides customers with high-purity alumina dispersions, achieving 4N–5N purity with impurity ions controlled to the ppm level. Furthermore, they offer high dispersion stability, with no settling for over six months, and even uniformity can be restored with a simple shake after transport. Furthermore, KOSNANO’s nano-alumina suspensions achieve a highly dispersed state, so upon contact with other surfaces, they chemically bond to the surface rather than adsorbing like conventional powders.
Dosage: The recommended dosage of nano-alumina dispersion is 0.5–10%. Users should determine the dosage based on individual system requirements through testing.
