Embodiment Construction

[0011] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on specific embodiments.

[0012] A low-temperature red glaze, the glaze used in it contains the following components and the mass percentage of each component: 65% silicon dioxide, 20% aluminum oxide, 0.05% iron sesquioxide, 2.8% potassium oxide, Sodium 2.3%, magnesium oxide 0.14%, calcium oxide 0.3%, selenium 6%, titanium oxide 0.01%, and the rest are unavoidable impurities, totaling 100%.

[0013] The preparation method of the low-temperature red glaze, the steps contained in the method are as follows:

[0014] S1: Prepare materials according to the components of the glaze and the mass parts of each component:

[0015] S2: According to the material: ball: water mass ratio = 1: 1.75: 1.5, wet ball milling for 19 to 21 hours;

[0016] S3: After the ball-milled glaze is sieved and iron-removed, it is adjusted to a glaze s...

Abstract

The invention discloses a low-temperature red glaze and a preparation method thereof. The components contained in the glaze used in the low-temperature red glaze and the mass percentages of each component are as follows: silicon dioxide 65%, aluminum oxide 20%, aluminum oxide Iron 0.05%, potassium oxide 2.8%, sodium oxide 2.3%, magnesium oxide 0.14%, calcium oxide 0.3%, selenium 6%, titanium oxide 0.01%, and the rest are unavoidable impurities, totaling 100%. The invention can greatly reduce the expansion coefficient of the glaze, so that the expansion coefficient of the glaze and the body can be matched, and the phenomenon of peeling off the glaze can be prevented.

Description

technical field [0001] The invention relates to a low-temperature red glaze and a preparation method thereof. Background technique [0002] At present, ceramic colored glazes are mainly some non-ferrous metal oxides, salts or double salts. Many colored glazes will decompose and lose color due to high-temperature calcination, but can only be colored at low temperatures, so they are called low-temperature colored glazes. After the decoration process, the glaze surface is bright and bright red, only low-temperature red / yellow glaze. However, the firing temperature of low-temperature red glaze is 750-950°C. At this temperature, the ceramic body must be fired with high-temperature glaze first, and then decorated with low-temperature red glaze. The glaze is peeled off during the process, causing defects. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a low-temperature red gl...
