Problems solved by technology

[0003] The glass-ceramics used in the traditional glass-ceramic composite plate is mainly composed of β-wollastonite as the main crystallite phase. There are many ceramic factories in the country that have practiced large-scale industrial production. The interface in contact with the particles crystallizes, so the size of the crystal flower depends on the size of the glass-ceramic particles, but in the production process of industrial ceramic factories, the particles are too large, and the large pores on the surface are difficult to eliminate
The growth of crystal flowers is difficult to break through the contact interface between particles, and it is also difficult to grow up, so the decorative effect appears monotonous

[0023] The preparation method of the crystalline glaze is as follows: first prepare the basic crystalline glaze: weigh the following raw materials in parts by weight to prepare the basic crystalline glaze: 20-40 parts of spodumene, 5-20 parts of quartz, 5-25 parts of calcite, 5 parts of talc ~25 parts, 5~20 parts of alumina, 1~5 parts of zinc oxide, 1~3 parts of sodium nitrate, 5~15 parts of zircon powder, 1~5 parts of bone ash, 1~5 parts of lithium carbonate, boric acid: 5~ 15 parts, the fineness of each of the above raw materials is less than 150 mesh;

[0024] The second step is to fully stir the above raw materials to obtain the basic crystalline glaze, and add coloring agent. The basic crystalline glaze and coloring agent are mixed evenly and then put into a glass tank furnace for melting. The melting temperature is 1450°C~1520°C. water quenching, drying, and sieving to obtain the crystalline glaze particles of 4 to 20 meshes. The crystalline glaze is mainly composed of β...

Abstract

The invention discloses a crystal glaze and its preparation method and use method. The crystal glaze is prepared by uniformly mixing a basic crystal glaze and one or more coloring agents, wherein the weight of the one or more coloring agents is 0 to 10% of the total weight of the basic crystal glaze and the one or more coloring agents; and the basic crystal glaze mainly comprises 2 to 40 parts of spodumene, 5 to 20 parts of quartz, 5 to 25 parts of calcite, 5 to 25 parts of talcum, 5 to 20 parts of alumina, 1 to 5 parts of zinc oxide, 1 to 3 parts of sodium nitrate, 5 to 15 parts of zircon powder, 1 to 5 parts of bone ash, 1 to 5 parts of lithium carbonate and 5 to 15 parts of boric acid. In melting of the basic crystal glaze of the crystal glaze, the one or more coloring agents are used and thus a composite ceramic tile adopting the crystal glaze has a bright color and strong stereoscopic impression and produces crystal patterns having diameters of 3 to 4 centimeters. The preparation method greatly reduces a firing period of the traditional crystal glaze and realizes industrial production. An experiment proves that a crystal glaze surface with large crystal patterns can be obtained in a firing period of only 75 minutes.

Description

technical field [0001] The invention relates to the technical field of surface glazes for ceramic products, in particular to a novel crystalline glaze and a preparation method and application method thereof. Background technique [0002] Traditional crystalline glazes are generally used for surface decoration of artistic ceramics or daily-use ceramic products. The production process is to grind various raw materials required for glaze making into glaze slurry, apply it to ceramic products, and fire at high temperature to make the glaze Under the action of the crystal nucleating agent in the high-temperature molten state, it crystallizes around the crystal nucleus and gradually grows up to form patterns of various shapes and sizes, so as to achieve the effect of decorating the surface of ceramic products. In order to achieve the ideal larger pattern, There must be sufficient firing time for the crystal flowers to grow, so the firing cycle takes several hours, or even dozens o...
