Abstract
A preparation method includes the following steps: Step (1): pressing and then drying body powder to form a green brick; Step (2): applying a ground coat on the surface of the green brick; Step (3): inkjet-printing a pattern on the surface of the green brick having the ground coat, and applying an isolation glaze; Step (4): applying a fully polished glaze on the surface of the green brick having the isolation glaze; and Step (5): drying, firing, and polishing the green brick having the fully polished glaze to obtain a hard wear-resistant polished glazed ceramic tile. The phase composition of the fired fully polished glaze is as follows: 10 to 20 percent by weight of corundum, 20 to 30 percent by weight of hyalophane, 0.5 to 1.0 percent by weight of hematite, and 50 to 68 percent by weight of amorphous phase.
