[0162] The same as Example 3, the only difference is that no nano-attapulgite is added to the additive.

[0163] Experimental Example 4:

[0164] The same as Example 3, the only difference is that no nano silica sol is added to the additive.

[0165] Experimental Example 5:

[0166] The same as Example 3, the only difference is that the sodium silicate solution in the additive is replaced by water.

[0167] The ceramic products of Experimental Examples 1-5 were placed in 3% hydrochloric acid mist for 12 hours, and then placed in 3% sodium hydroxide alkaline mist for 12 hours, and the acid and alkali stability under the mass fraction of 3% was tested. The products were placed in 8% hydrochloric acid mist for 12 hours, and then placed in 8% sodium hydroxide alkaline mist for 12 hours, and the acid and alkali stability under the mass fraction of 8% was tested. The test results are shown in Table 3.

[0168] Table 3 Performance test results of the products of Experimental Examples 1-5 under acid and alkaline conditions:

[0169] It can be seen from Experimental Examples 1-5 that when no nano-attapulgite and no silica powder were added to the additives, the performance of the ceramic products showed a more obvious trend of deterioration. At the same time, when no yttrium oxide and nano-silica sol were added to the additives, and the sodium silicate solution was replaced by water, the performance of the ceramic products showed a trend of deterioration. The additives obtained by the specific method of the present invention have the most obvious performance effect on the ceramic products, and the effects of other methods are not as significant as those of the present invention.

[0170] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.

[0171] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
