[0053] Comparative Example 1

[0054] By weight, 40 parts of quartz, 5 parts of kaolin, 15 parts of potassium feldspar, 25 parts of sodium feldspar, 7 parts of wollastonite, 6 parts of zirconium oxide, 1 part of titanium oxide, and 1 part of hydroxymethyl cellulose were weighed, and the remaining steps were the same as in Examples 1-3, to prepare sanitary ceramics without a skin-feel glaze.

[0055] Comparative Example 2

[0056] By weight, 27 parts of quartz, 11 parts of zinc acetate, 5 parts of kaolin, 13 parts of potassium feldspar, 25 parts of sodium feldspar, 4 parts of wollastonite, 2 parts of titanium dioxide, 5 parts of cerium acetate, 7 parts of graphene, and 1 part of hydroxymethyl cellulose were weighed to prepare sanitary ceramics without a skin-feel glaze.

[0057] Comparative Example 3

[0058] By weight, weigh 10 parts of quartz, 26 parts of alumina, 4 parts of kaolin, 20 parts of potassium feldspar, 21 parts of sodium feldspar, 4 parts of wollastonite, 2 parts of titanium dioxide, 5 parts of cerium acetate, 7 parts of graphene, and 1 part of hydroxymethyl cellulose. The remaining steps are the same as in Examples 1-3 to prepare sanitary ceramics without a skin-feel glaze.

[0059] Comparative Example 4

[0060] Weigh out 40 parts by weight of quartz, 26 parts by weight of zinc acetate, 5 parts by weight of kaolin, 15 parts by weight of potassium feldspar, 25 parts by weight of sodium feldspar, 7 parts by weight of wollastonite, 2 parts by weight of titanium dioxide, 5 parts by weight of cerium oxide, 7 parts by weight of graphene and 1 part by weight of hydroxymethyl cellulose, and follow the same steps as in Examples 1-3 to obtain sanitary ceramics without a skin-feel glaze.

[0061] The glaze of the sanitary ceramic prepared in Example 3 was tested by scanning electron microscopy. The scanning electron micrographs are shown below. Figure 1 As shown. Additionally, scanning electron microscopy (SEM) was performed on the glaze of sanitary ceramics prepared in a specific ratio of zinc acetate, cerium acetate, and graphene (not containing the components of this application) in Comparative Example 1. The SEM images are shown below. Figure 2 As shown; the glaze of the sanitary ceramic prepared in Comparative Example 2, which does not contain zinc acetate, cerium acetate, and graphene in a specific ratio according to this application, was subjected to scanning electron microscopy (SEM) analysis, and the SEM images are shown below. Figure 3 As shown; the glaze of the sanitary ceramic prepared in Comparative Example 3, which does not contain zinc acetate, cerium acetate, and graphene in a specific ratio according to this application, was subjected to scanning electron microscopy (SEM) testing, and the SEM images are shown below. Figure 4As shown; and scanning electron microscopy (SEM) analysis of the glaze of sanitary ceramics prepared in a specific ratio of zinc acetate, cerium acetate, and graphene (not containing the present application) in Comparative Example 4, the SEM images of which are shown below. Figure 5 As shown.

[0062] from Figure 1 As can be clearly seen in Example 3 of this application, the sanitary ceramic glaze has a rich structural texture. It feels warm and delicate to the touch, providing excellent tactile and visual appeal. This is precisely what this application achieves by using a specific combination of zinc acetate, cerium acetate, and graphene along with other components. In this application, zinc acetate crystallizes after sintering to achieve a matte glaze. Conversely, while alumina can also crystallize, it does not achieve a matte glaze. The use of graphene and cerium acetate, sintered at high temperature, combined with the matte finish imparted by zinc acetate, allows for the display of rich structural textures, resulting in a warm and delicate glaze texture and an excellent tactile feel.

[0063] On the contrary, such as Figures 2-5 It can be seen that Comparative Examples 1-4, lacking the specific proportions of zinc acetate, cerium acetate, and graphene, produced sanitary ceramics with virtually no texture on the glaze, resulting in a rough and uneven surface, leading to a rough feel and poor tactile and aesthetic appeal. For example, Figure 5 The glaze surface made from components including zinc acetate, cerium oxide, and graphene shows numerous pores and is rough and uneven, without any texture.

[0064] While the embodiments disclosed in this application are as described above, the content is merely for the purpose of facilitating understanding of this application and is not intended to limit this application. Any person skilled in the art to which this application pertains may make any modifications and changes in the form and details of the implementation without departing from the spirit and scope disclosed in this application; however, the scope of protection of this application shall still be determined by the scope defined in the appended claims.
