Abstract
The invention discloses a Qilan glaze and a preparation method thereof, wherein the Qilan glaze is prepared from the following raw materials in parts by weight: 40-48% of albite, 18-25% of quartz powder, 8-12% of kaolin and 21-25% of wollastonite. Has the advantages that: the porcelain fired by the glaze material has the advantages of condensed color and luster, uniform thickness, stable color generation, no glaze surface flow and crack, smooth hand feeling, durability, wear resistance, good smoothness and thermal stability, wide firing range, suitability for medium-temperature oxidizing atmosphere and high-temperature reducing atmosphere and wide popularization.
Description
Technical Field
The invention relates to the technical field of glaze materials, in particular to a Qilan glaze material and a preparation method thereof.
Background
The treasure of the traditional Chinese porcelain making process. Also known as "blue glaze", "sacrificial blue glaze" and "celadon". Both bright and clear blue glazes are known as "celadon", a high temperature lime alkali glaze. Glazing the green body and sintering at high temperature. Deep color, no cracking of glaze surface, uniform color tone and stable color. The color of the glaze blue is as deep sea, the glaze is clean and uniform, the color is stable, the glaze is called as 'common celadon', the color is stable and bright as precious stone, and the glaze is also called as 'top grade' of Xuande color glazed porcelain by juxtaposing the glaze blue with white glaze and red glaze. The craft inherits the original tradition, the burning is continuously prolonged, and the main modeling is sacrificial wares and porcelain for display.
In recent years, although an energy dispersion X-ray fluorometer and a colorimeter are used in the text "composition and chromaticity characteristics of the blue glaze of the tubular kiln. But does not relate to the manufacture of celadon and process recovery studies. In addition, no relevant report on the preparation process of the chemical celadon glaze is found.
Disclosure of Invention
The invention aims to solve the problems and provide a flush glaze.
The invention realizes the purpose through the following technical scheme:
the glaze material comprises the following raw materials in proportion: 40-48% of albite, 18-25% of quartz powder, 8-12% of kaolin and 21-25% of wollastonite.
Further, the material composition comprises the following raw materials in proportion: 44.9 percent of albite, 22.6 percent of quartz powder, 9.1 percent of kaolin and 23.4 percent of wollastonite.
The invention also provides a preparation method for preparing the zilan glaze, which comprises the following steps:
s1, weighing the raw materials according to the proportion;
s2, respectively pouring the raw materials weighed in the step S1 into a ball milling tank for ball milling treatment;
s3, filtering, namely filtering the ball-milled raw materials through a superfine screen and mixing the filtered raw materials;
and S4, adding water according to the component weight requirement, and uniformly mixing.
Further, in the step S2, in the ball milling process, each raw material needs to be finely milled for 18 to 21 hours.
Further, in the ball milling process in step S2, the balls: material 2: 1.
Further, in the step S3, the mesh size of the ultrafine screen used in the filtering operation is 270-500 meshes.
The application process of the zilan glaze material on the ceramic product comprises the following steps: in the drying stage, the temperature is raised by slow fire for 2 to 3 hours to raise the temperature of the kiln from room temperature to 570-580 ℃ and then raised to 600 ℃ within 0.5 hour; then entering an oxidation stage, heating to 850-950 ℃ within 3-4 hours at the oxidation stage, and keeping the temperature for 20 minutes; then transferring to a strong reduction stage, and heating to 1100-1150 ℃ within 1-1.5 hours in the strong reduction stage; then, transferring to a weak reduction stage, and heating to the sintering temperature of 1200-1300 ℃ within about 1 hour at the stage; then transferring to a cooling stage, wherein the temperature is quickly cooled to 140-160 ℃ within 10 minutes, and then the temperature is naturally cooled to room temperature.
The albite contains Na2O·Al2O3·6SiO2。
The quartz powder comprises SiO2。
The kaolin contains Al as component203·2Si02·2H20。
The wollastonite comprises CaSiO3Or CaOSiO2。
The formula of the glaze material of the invention takes the expansibility of the porcelain blank into consideration, so that the expansion coefficient of the glaze is matched with that of the blank. On one hand, the method can quickly complete physical and chemical reactions at medium temperature, and the physical and chemical reactions are well combined with a green body and wrapped on the surface of a porcelain body, so that the fired zilan glazed porcelain meets the process requirements.
The invention has the beneficial effects that: the porcelain fired by the glaze material has the advantages of condensed color and luster, uniform thickness, stable color generation, no glaze surface flow and crack, smooth hand feeling, durability, wear resistance, good smoothness and thermal stability, wide firing range, suitability for medium-temperature oxidizing atmosphere and high-temperature reducing atmosphere and wide popularization.
