Latest Patents

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