Document Type and Number:
Japanese Patent JP5765455
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a novel antibacterial ceramic industry product capable of obtaining efficient antibacterial property even with reducing the used amount of an antibacterial metal than conventional because utilization efficiency of the antibacterial metal is high, and to provide a ceramic industry surface treatment agent capable of being used for manufacturing the antibacterial ceramic industry product and a manufacturing method of the antibacterial ceramic industry product using the ceramic industry surface treatment agent.SOLUTION: There is provided an antibacterial ceramic industry product having metal nanoparticles having an average particle diameter of 200 nm or less containing at least silver on a surface. A ceramic industry surface treatment agent is obtained by colloidal dispersing metal nanoparticles having 90% cumulative diameter Dof a particle size distribution of 150 nm or less in a dispersion. A manufacturing method includes firing at 800 to 1600°C after applying the ceramic industry surface treatment agent to the surface of the ceramic industry product.
