  • Publication number: 20180148383
    Abstract: A ceramic surface treatment method includes the following steps. An antibacterial ion and a sol-gel solution containing a silane compound are mixed to form a treatment solution. Next, a ceramic substrate is placed in the treatment solution to perform a treatment bonding reaction such that the antibacterial ion in the treatment solution can be grafted to the surface of the ceramic substrate via the silane compound. Next, a sintering condensation reaction is performed on the ceramic substrate after the treatment bonding reaction to form a protective film on the surface of the ceramic substrate. The protective film is attached to the surface of the ceramic substrate via a hydrophobic layer, and the antibacterial ion is spread on the hydrophobic layer.
