Abstract

The invention provides lava black brick glaze and a preparation method and application thereof.The prepared lava black brick glaze comprises first slurry and second slurry, the first slurry and the second slurry are used in cooperation, and the expansion coefficient of the first slurry is 5.79 * 10 <-6 > / DEG C-6.15 * 10 <-6 > / DEG C; the initial melting temperature of the first slurry is 1110-1180 DEG C; the particle size of the first slurry is 3-9 [mu] m; the expansion coefficient of the second slurry is 6.12 * 10 <-6 > / DEG C to 7.15 * 10 <-6 > / DEG C; the initial melting temperature of the second slurry is 1000-1150 DEG C; and the particle size of the second slurry is 3-9 [mu] m. By optimizing the components and the component proportion, the formula design is more stable, the obtained first slurry has a better combination effect when being in contact with a blank body, and a formed glaze surface is low in roughness, high in glossiness, low in porosity and excellent in wear resistance.

Description

technical field [0001] The invention relates to the technical field of architectural ceramics, in particular to a lava black brick glaze and its preparation method and application. Background technique [0002] Glaze is a thin colorless or colored glassy layer covering the surface of ceramic products. The thickness of the glaze layer is generally 200-8000μm. The glaze layer is prepared by grinding mineral raw materials and specific chemical raw materials in a certain proportion. The glaze slurry is applied on the surface of the embryo body and formed by calcination. The glaze layer can improve the performance of the surface of the ceramic body, such as making the ceramic surface smoother, increasing the mechanical strength, reducing the surface porosity, increasing the corrosion ability, and especially beautifying the appearance of the product. However, in the prior art, due to the poor performance of the preparation of the glaze material, the surface smoothness, mechanical...
