Problems solved by technology

Although this method of glaze firing is not affected by the atmosphere, it needs to be used in lime glaze that does not contain zinc, and the color is affected by Co 2 o 3 Influenced by the price of raw materials, etc., the cost is very high
[0003] In recent years, some scholars have made Co-free Fe-Cr-Mn-Ni system black materials and Fe-Cr-Cu-Ni system black materials (Sun Chen, Yin Shujian, Dai Jun, Dong Bo, Zhang Yuhong. Cob

Abstract

A method for preparing split-phase black fancy glaze by utilizing industrial slag includes evenly grinding slag coarse materials in a mortar, filling the ground slag coarse materials into a crucible, roasting the materials in a high temperature furnace to 1000 DEG C, conducting heat preservation for 60 minutes, enabling the materials to be naturally cooled, conducting ball grinding after cooling, conducting screening through a 80-mesh screen to prepare fine slag, mixing feldspar, quartz, calcite, talc, calcium phosphate, fine slag, sodium tripolyphosphate and CMC, conducting fine grinding to 250 meshes, modulating glaze slip to be 1.7g/cm<3>, evenly spreading the glaze slip on a base, heating the glaze slip to 1180 DEG C to 1250 DEG C, conducting heat preservation for 20 to 50 minutes, and then conducting natural cooling. Split mechanism and slag coloring oxide generated by a melt in the roasting process of the glaze slip are combined to conduct coloring and enable a little color oxide to generate strong coloring capability. The preparation method of the black fancy glaze is low in cost, high in stability and abundant in decorative pattern. Further, colorant content of the black fancy glaze is 30% to 50% of color material content in common glaze.

Description

technical field [0001] The invention relates to a preparation method of phase-separated black flower glaze using industrial slag, in particular to a preparation method of black flower glaze applicable to building sanitary ceramics, daily ceramics, art ceramics and other high, medium and low temperature ceramics. Background technique [0002] Black glaze is a precious glaze. Decorating porcelain with black glaze is an ancient and traditional method in my country. The Shangyu black glaze of the Eastern Han Dynasty and the Deqing kiln black glaze of the Eastern Jin Dynasty have always been loved by people for their dignified, solemn and steady color characteristics. These black glazes are made by firing iron-containing clay in a reducing atmosphere. Its color is extremely unstable, and the firing process is difficult to master. With the development of modern ceramic industry, Co 2 o 3 , Fe 2 o 3 、Cr 2 o 3 , Mn 2 o 3 The metal oxides are first prepared into pigments, an...
