Detailed Description
The invention is further illustrated by the following detailed description, which is to be understood as being merely illustrative of the invention and not limiting thereof. Unless otherwise specified, each percentage refers to a mass percent.
First, the invention provides a cerium-tin-zinc system crystal glaze rich in colored particles. The raw material composition of the cerium tin zinc crystal glaze rich in the colored particles comprises cerium tin zinc crystal glaze and colored dry particles.
The chemical composition of the cerium tin zinc crystal glaze comprises: in mass percent, siO 2 ：46～50％、Al 2 O 3 ：6～9％、CaO：4.0～6.0％、MgO：1.0～2.0％、K 2 O：0.5～1.5％、Na 2 O：4.0～6.0％、ZnO：23～27％、F：1.5～3.5％、CeO 2 ：0.5～3.5％、SnO 2 ：0.5～3.5％。
The technical proposal disclosed by the invention is that SnO is simultaneously introduced into cerium tin zinc crystal glaze 2 、CeO 2 The crystal nucleus agent such as fluoride and the like can realize stable crystallization under the low-temperature rapid-sintering process condition, and simultaneously the sintered glaze has the three-dimensional effect of white crystal flowers and colored particles. SnO (SnO) 2 、CeO 2 Higher coordination number of the iso-oxide and Sn 4+ 、Ce 4+ The cation field is strong, and tin oxide and cerium oxide are easy to be separated out from silicate network in the cooling process or SnO rich with about 5nm is generated 2 、CeO 2 Thereby inducing nucleation of silicate melt. At the same time, the fluoride will also separate from the melt during cooling, forming a fine crystalline precipitate that introduces glass opacification. The principle of fluoride emulsion glass is utilized to promote glass nucleation, wherein fluoride microcrystal is the nucleation center of the glass. At the same time due to two F - Ion-substituted O 2- The ion reaches electrical neutrality, reflecting that it is structurally equivalent to the substitution of one silicon-fluorine bond (≡Si-O-Si≡) with two silicon-fluorine bonds (≡Si-F). The presence of Si-F groups means that the breakage of the silica network leads to weakening of the glass structure, inducing devitrification of the glass. In some embodiments, the initial melting temperature of the cerium tin zinc crystalline glaze is 950 to 1000 ℃.

If the content of the colored dry particles exceeds 10%, more small crystal flowers which are invisible to the naked eyes are precipitated on the glaze surface, so that the glaze layer presents an opaque and opaque state; in addition, the color dry particle content is too high, which can cause the glaze layer to cover the color and texture of the ink-jet pattern, and the artistic effect of combining the ink-jet pattern with crystal flowers and color particles cannot be presented. If the content of the colored dry particles is less than 5%, white crystal flowers with larger sizes can be precipitated on the glaze, but the crystal flowers are overlapped to cover the colors and textures of the ink-jet patterns, and the artistic effect of combining the ink-jet patterns with the crystal flowers and the colored particles can not be fully exhibited.

(3) And (5) spraying surface glaze. And (3) applying overglaze on the surface of the dried green brick in the step (2) in a glaze spraying mode. The overglaze formula commonly used in the art is adopted. As an example, the raw material composition of the overglaze includes: the potassium feldspar comprises the following components in percentage by mass: 35%, albite: 25%, kaolin: 25% of zirconium silicate: 10% of calcined alumina: 5%. The chemical composition of the overglaze comprises: in mass percent, siO 2 ：55.45％、Al 2 O 3 ：25.77％、Fe 2 O 3 ：0.31％、TiO 2 ：0.14％、CaO：0.26％、MgO：0.20％、K 2 O：4.36％、Na 2 O：2.74％、ZrO 2 :6.31%, loss on ignition: 4.22%. The effect of applying the overglaze is to mask the base color and imperfections of the blank and promote the color development of the inkjet pattern.
In some embodiments, the specific gravity of the glaze of the colored overglaze can be controlled to be 1.44 to 1.46, and the glazing amount is 450 to 550g/m 2 . The specific gravity of the overglaze is too high, the uniformity of glaze spraying is poor, and the smoothness of the glaze is poor; the specific gravity of the overglaze is too low, the uniformity of glaze spraying is better, but the introduced moisture content is too high, and the broken brick of the glaze line is easy to generate. The overglaze glazing amount is too high, the effect of covering the blank body is in a supersaturated state, and no obvious gain effect exists; the overglaze is too low in glazing quantity, the effect of covering the base color of the green body is poor, and the color development of ceramic ink is not utilized.

In some embodiments, the ball milling may also be performed with the addition of additives such as suspending agents, binders, and the like. The suspending agent and the binder are suspending agents and binders commonly used for slurry in the ceramic field. The suspending agent and the binder are used in an amount to satisfy the specific gravity and the flow rate required by the final glazing. When the cerium tin zinc crystal glaze is used, the cerium tin zinc crystal glaze can be used in the form of glaze slip, or can be used in the form of dry grains.

The specific gravity and the flow rate are too low, and the fluidity of the glaze slurry is too good, so that the glaze curtain for spraying glaze is easy to drift, and the glazing quantity is uneven and unstable; the specific gravity and the flow rate are too high, the fluidity of the glaze slurry is too poor, and the glaze is easy to have egg-shaped lack of glaze in the process of glazing. The glazing quantity is too low, and the crystal flowers formed after firing are smaller and the quantity is small; the glazing quantity is too high, the crystal flowers formed after firing are large and large in quantity, the crystal flowers are easy to be overlapped together, the color and the texture of the ink-jet pattern are covered, and the artistic effect of the combined ink-jet pattern and crystal flowers cannot be fully displayed.
