Abstract
The present invention concerns a process for manufacturing nanoparticles in a slurry based on an aqueous solvent by treating said inorganic particles or their agglomerates in said solvent at a solids content of 30-75w-%, by adding dispersing agent(s) and by carrying out ultrasonic treatment at an intensity of 5-1000 W/cm2 on this concentrated slurry. Thereby, a homogenous consistent particle slurry is obtained.
Claims20
A process for manufacturing nanoparticles in a slurry based on an aqueous solvent by dispersion of inorganic particle agglomerates, wherein treating said inorganic particles or their agglomerates in said aqueous solvent at a solids content of 30-75 w-% by adding dispersing agent(s) and by carrying out ultrasonic treatment at an intensity of 5-1000 W/cm2 on the concentrated slurry, whereby a stabilized and dispersed concentrated slurry is obtained.
A slurry of inorganic nanoparticles in an aqueous solvent, wherein it contains the dispersed nanoparticles having a mean particle diameter of about 200 nm.
