The ceramic prepared by the invention is subjected to water absorption test, 5 ceramic sheets are taken, cleaned and dried, the weight of the ceramic sheets is weighed respectively, then the ceramic sheets are separated and placed in distilled water, the distilled water is boiled for 3 hours, the water surface is kept higher than the ceramic sheets by more than 10mm, then the ceramic sheets are fished out, water attached to the surfaces of the ceramic sheets is wiped off by cloth which is saturated with water, the weight of the ceramic sheets is weighed respectively and rapidly, then the water absorption of each ceramic sheet is calculated by a formula, and the average water absorption of the ceramic sheets is calculated to be 0.15%, namely the water absorption of the medium-low temperature fired ceramic product prepared by the embodiment is 0.15%.
The results of the water absorption tests on the medium and low temperature fired ceramic articles prepared in examples 1 to 5 above and the medium and low temperature fired ceramic articles of the prior art are shown in the following table:
as can be seen from the above examples, the water absorption of the medium and low temperature fired ceramic products obtained in examples 1 to 3 is 0.2% or less as a whole, and the water absorption of the medium and low temperature fired ceramic product obtained in example 2 is the lowest and the best effect is obtained.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described above, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
