Problems solved by technology

However, due to the limitation of the performance of the oxide itself, the color glaze colored by oxides also has a big bottleneck in glaze production.
For example, in the preparation of medium-temperature lead-free color glaze, when the coloring oxide reaches a certain proportion, it is very easy to cause a series of defects such as ripples, glaze bubbles, uneven color, and even metallic luster on the glaze surface after firing. Make bright, uniform, soft, stable oxide colored glazes suitable for mass production

Abstract

The invention provides lead-free frit base glaze beneficial for color development of coloring oxides. The lead-free frit base glaze is formed by mixing lead-free coloring frit and lead-free base frit.The formula of the lead-free coloring frit includes 49.7-49.9 of SiO2, 7.6-7.8 of Al2O3, 2.0-2.2 of K2O, 2.5-2.7 of Na2O, 6.9-7.1 of CaO, 0.2-0.4 of MgO, 2.8-3.0 of BaO, 2.4-2.6 of ZnO, 5.4-5.6 of B2O3 and 20.0-20.2 of coloring oxides. The formula of the lead-free base frit includes 53.8-54.0 of SiO2, 9.6-9.8 of Al2O3, 3.1-3.3 of K2O, 2.4-2.6 of Na2O, 11.2-11.4 of CaO, 0.4-0.6 of MgO, 1.8-2.0 ofBaO, 6.8-7.0 of SrO, 1.6-1.8 of Li2O and 8.7-8.9 of B2O3. The lead-free frit base glaze is high in melting property and stability, bright, uniform, soft and stable in color and luster and suitable formass production.

Description

technical field [0001] The invention mainly relates to the technical field of ceramic glazes, in particular to a lead-free frit base glaze which is beneficial to the color development of colored oxides. Background technique [0002] At present, ceramic color glazes in the industry are basically colored by pigments and oxides. The glaze colored by the pigment has been calcined at a high temperature, so it is easier to obtain a stable effect for the colored glaze. However, due to the limitation of the performance of the oxide itself, the color glaze colored by oxides also has a great bottleneck in glaze production. For example, in the preparation of medium-temperature lead-free color glaze, when the coloring oxide reaches a certain proportion, it is very easy to cause a series of defects such as ripples, glaze bubbles, uneven color, and even metallic luster on the glaze surface after firing. Make bright, uniform, soft, stable oxide colored glazes suitable for mass production...
