Abstract: As ceramics are widely used in public places, the antifouling and cleaning performance of their glazes have an important impact on public hygiene. The effects of ZrSiO4 dosage (10 wt.%-40 wt.%) and sintering temperature (1150 ℃-1210 ℃) on microstructure, whiteness, gloss and antifouling properties of the glazes were studied. Finite element method was used to analyze the effects of microstructure of the glaze on the spread of the pollutant droplets and water washing. It was found that the samples with 40 wt.% ZrSiO4 had the lowest gloss and the highest whiteness, at given temperatures, but they all had excellent antifouling properties, due to the micropapillary structure on their surface. Samples with such a structure not only inhibited high spread of pollutant droplets, but also had stronger clean ability, as compared with those having micro groove structure. Therefore, by constructing micropapillary structure on the surface of the matt glaze, both the matt performance and antifouling/cleaning performance could be enhanced.
