摘要：
Glazes have great influence on most of the final properties of sanitary wares, such as color, glossy, and surface roughness. Generally, these properties have been changed by chemical composition and firing parameters. In addition, the selection of particle-size distribution of raw glaze can affect on the surface appearance and cleanability of glazed surface. In this paper, raw glazes were milled in ball mill for different time. Prepared glaze slurry was applied to green bodies, later dried and fired. The same glaze was also uniaxially pressed to form cylindrical sample; the specimen was placed on substrate surface and fired in hot stage microscope. The glaze evolution upon heating was recorded by CCD camera, the contact angle between molten glaze and substrate was measured to determine the wettability. The results showed that particle-size distributions have great influence on the melting behavior of glaze and the surface appearance of glazed ceramics.
