Latest Patents

Mihara holds a patent for a process for preparing mono-dispersed particles. This process involves creating spherical particles of hydroxide with a particle diameter ranging from 0.1 to 10 micrometers. The method includes adding a metal alkoxide to a water-alcohol dispersion containing a metal oxide or hydroxide seed under alkaline conditions. A key improvement in this process is maintaining a constant pH between 10 and 13 during the addition of the metal alkoxide, which helps in achieving particles that are substantially free from aggregation and have a sharp size distribution. The resulting white particles can be heat-treated to produce black particles, which may also be coated with synthetic resin for enhanced utility.
