With economic development and rising living standards, people's demands for a higher quality of life are increasing. Consumers are increasingly demanding the performance of household ceramics, sanitary ceramics, and architectural ceramics, demanding not only aesthetics but also density, strength, practicality, and wear resistance. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a baby's breath powder glaze ceramic and its processing technology, so that the ceramic crafts have a good baby's breath effect on the brick surface under fluorescent light or sunlight, and have excellent strength and mechanical properties.

[0004] In order to achieve the above object, the present invention provides the following technical solutions:

[0005] A baby's breath powder glaze ceramic comprises the following components in parts by weight: 10-20 parts of magnesia-alumina spinel, 20-30 parts of potassium feldspar, 30-40 parts of zirconium oxide, 4-6 parts of cerium oxide, 12-15 parts of composite gold chloride, 5-8 parts of a binder, 7-10 parts of sodium silicate and 8-10 parts of talc.

[0009] S2: adding a binder and composite gold chloride to the above mixture to form a blank with a slurry viscosity of 400-450 mPa·s, shaping the blank, and drying it at 65-70°C to obtain a blank;

[0010] S3: Firing the green body obtained in step S2 to obtain starry sky powder glaze ceramics.

[0011] Preferably, the preparation method of the composite gold chloride in step S1 comprises:

[0012] S11: preparing composite kaolin solution;

[0013] S12: adding a 55% by mass polyvinyl pyrrolidone aqueous solution and gold chloride to the composite kaolin solution obtained in step S11, continuing stirring for 30 minutes, and drying at 60-70° C. to obtain composite gold chloride.

[0014] Preferably, the weight ratio of the polyvinyl pyrrolidone aqueous solution, gold chloride and composite kaolin solution in step S12 is 1:1:5.

[0015] Preferably, the method for preparing the composite kaolin solution in step S11 includes:

[0016] S21: kaolin and 65% urea solution were mixed and stirred at 60°C for 24 h;

[0017] S22: mixing the mixed solution obtained in S21 with 80% by mass of hydrazine hydrate, stirring and reacting at 45-55° C. for 12-15 hours to obtain a primary composite solution;

[0018] S23: Mix the primary composite solution obtained in step S22, dimethyl sulfoxide, potassium iodide, a 45% by volume sulfuric acid solution, and hydrogen peroxide, and stir the mixture at 30-35° C. for 12-15 hours to obtain a composite kaolin solution.

[0023] The present invention modifies the gold chloride and composite kaolin solution to increase the interlayer spacing, allowing the gold chloride to enter between the kaolin layers, and better achieves inlaying with other raw materials through the cross-linking effect of polyvinyl pyrrolidone, so that a uniform concave-convex effect is formed on the surface of the tile due to differences in melting point, viscosity and fluidity during the firing process, thereby forming a star-shaped effect. In addition, the close cross-linking makes the density between the components relatively high, and the relative density of the grain boundary of the green body is also high by gradually increasing the temperature. The green body is further kept warm for a long time by lowering the temperature, so that the reaction inside the green body is carried out more thoroughly, and finally the grains are finer, so as to have good mechanical properties.
