SUPER-SMOOTH GLAZE AND PREPARATION METHOD THEREOF

Abstract

The present invention relates to a super-smooth glaze and a preparation method thereof, and belongs to the field of ceramic machining, wherein each component in parts by weight is: potassium feldspar, quartz, kaolin, calcite, dolomite, boric acid, aluminum oxide, silicon oxide, calcium oxide, potassium oxide, sodium oxide, zinc oxide, and barium oxide; a mixture weighed in proportion is disposed in a planetary quick ball mill, and pure water of 30˜40 wt % to the total weight of the mixture is added to ball-mill the mixture to particle sizes of 0.5˜1.0 μm, thus obtaining the super-smooth glaze. The method enables the surface of a glaze layer to be highly smooth and makes the roughness of the glaze be relatively reduced than that of an ordinary ceramic glaze.
