Embodiment 1
[0025] This embodiment 1 provides a fluorescent glaze, the raw materials of which include, by weight, 70 parts of long-lasting phosphor powder; 40 parts of borax; 3 parts of glass powder; and 0.8 part of zinc oxide. The preparation method of the fluorescent ceramic product made from the fluorescent glaze is as follows:
[0026] (1) Mix the components of the raw materials evenly, mix them in the ratio of material: ball: water = 1:2:0.8, put them in a ball mill for ball milling for 8 hours, add water to the mixture after ball milling to make a glaze slurry, and age for 3 hours , get fluorescent glaze;
[0027] (2) Coating the above-mentioned fluorescent glaze on the surface of a non-glazed ceramic product, putting it into an electric furnace, calcining at 950° C., and then cooling naturally to obtain the fluorescent ceramic product.
Embodiment 2
[0029] This embodiment 2 provides a fluorescent glaze, and its raw materials include, by weight, 60 parts of long-lasting phosphor powder; 38 parts of borax; 2 parts of glass powder; and 0.5 part of zinc oxide. The preparation method of the fluorescent ceramic product made from the fluorescent glaze is as follows:
[0030] (1) Mix the components of the raw materials evenly, mix them in the ratio of material: ball: water = 1:2:0.8, put them in a ball mill for ball milling for 6 hours, add water to the mixture after ball milling to make a glaze slurry, and age for 4 hours , get fluorescent glaze;
[0031] (2) Coating the above-mentioned fluorescent glaze on the surface of the finished ceramic product without glaze, putting it into an electric furnace for calcination at 900° C., and then cooling naturally to obtain the crude fluorescent ceramic;
[0032] (3) Coating transparent glaze on the surface of the rough fluorescent ceramic product, calcining at 880° C., and then cooling ...
Embodiment 3
[0035] Embodiment 3 provides a fluorescent glaze, and its raw materials include, by weight, 50 parts of long-lasting phosphor powder; 30 parts of borax; 5 parts of glass powder; and 1 part of zinc oxide. The preparation method of the fluorescent ceramic product made from the fluorescent glaze is as follows:
[0036] (1) Mix the components of the raw materials evenly, mix them in the ratio of material: ball: water = 1:2:0.8, put them in a ball mill for ball milling for 4 hours, add water to the mixture after ball milling to make a glaze slurry, and stale for 3.5 hours , get fluorescent glaze;
[0037] (2) Spray the above-mentioned fluorescent glaze on the surface of the glaze-free ceramic product, put it into an electric furnace, calcinate at 900° C., and then cool naturally to obtain the fluorescent ceramic product.
