More Information
Summary:The invention relates to a medium-temperature daily double-sided crack glaze ceramic and a preparation method. The medium-temperature daily double-sided crack glaze ceramic comprises a preform body and glaze, the preform body is prepared from the following chemical ingredients in mass percent: 57-59% of SiO2, 30-35% of Al2O3, 0.1-0.5% of CaO, 2-2.5% of MgO, 3-3.5% of K2O and 0.1-0.5% of Na2O, and the breaking strength is 100-120MPa; the preparation method of the medium-temperature daily double-sided crack glaze ceramic comprises the following steps: enabling the preform body to be manufactured into a green body, glazing, drying, then carrying out firing treatment, wherein the firing temperature is 1,260-1,280 DEG C, preserving heat for 20-25min, cooling naturally, then preserving the heat for 30min when the temperature drops to 1,100 DEG C, and then cooling continuously to obtain the medium-temperature daily double-sided crack glaze ceramic. The medium-temperature daily double-sided crack glaze ceramic increa
