Alumina Sol
Alumina sol is a colloidal solution of baemite nanoparticles dispersed in a solvent. We have established crystal shape control technology based on our core technology of nanoparticle synthesis, and offer alumina sol in various shapes, such as columnar, plate, and fiber.
Alumina sols are characterized by high transparency and high purity. Alumina sols are used in a wide range of applications such as inorganic binders, filler agents, coating agents, and surface treatment agents for thermal, chemical, and mechanical protection and modification. In particular, fibrous Boehmite nanofibers, when added to resins as fillers, are effective in suppressing thermal expansion, improving heat resistance, and increasing elastic modulus. Its high adhesiveness also makes it suitable for use as a binder in nonwoven fabrics and for particle immobilization.
