Problems solved by technology

[0004] When the glaze is fired at high temperature, the organic matter in the glaze is oxidized to produce gas. If the gas is not removed before the glaze is melted, many pores will appear on the glaze surface. If the glaze is melted, the surface tension is too high, which will cause ripples on the glaze surface. Orange peel ,Affect the appearance

Abstract

The embodiment of the invention discloses a formulation and a sintering method for ultra-flat glaze, applying to the field of industrial production. The formulation comprises potash feldspar, calcite, quartz, kaolin, zinc oxide, barium carbonate and calcined kaolin, wherein the total content of AL2O3 in the formulation is 12-15%, the contents of solvents are 4.3-4.8%, and the solvents include K2O, NA2O, CaO, ZnO and BaO. According to the embodiment disclosed by the invention, the surface of the glaze can be flatted and smoothened, and pores are reduced.

Description

technical field [0001] The invention relates to the technical field of industrial production, in particular to a super-flat glaze formula and a firing method. Background technique [0002] The surface of ceramic products is usually protected by a thin layer of glaze to make the surface smooth, avoid dirt and moisture absorption, and play a decorative effect. [0003] In the prior art, the formula of the glaze includes potassium feldspar, calcite, quartz, kaolin, talc, zinc oxide, barium carbonate and calcined kaolin, wherein the ingredients as flux in the formula include: K 2 O, Na 2 O, CaO, MgO, ZnO and BaO. [0004] When the glaze is fired at high temperature, the organic matter in the glaze is oxidized to produce gas. If the gas is not removed before the glaze is melted, many pores will appear on the glaze surface. If the glaze is melted, the surface tension is too high, which will cause ripples on the glaze surface. Orange peel ,Affect the appearance. Contents of th...
