Latest Patents

Hayakawa holds a patent for a "Method for manufacturing hexagonal plate-shaped zinc oxide particles." This method provides a way to produce hexagonal plate-like zinc oxide particles with a sharp particle size distribution, ensuring a relatively uniform particle size at a high weight yield and percent yield. The process involves mixing an aqueous hexamethylenetetramine (HMT) solution with an anionic surfactant solution in a water-insoluble organic solvent, and optionally water, to create a microemulsion. An aqueous zinc salt solution is then added dropwise to this microemulsion, which is heated to a reaction temperature of 80°C or more, without the use of an autoclave, to form the desired zinc oxide particles.
