The invention relates to an ink-jet penetrated polished semitransparent
ceramic sheet. The ink-jet penetrated polished semitransparent
ceramic sheet comprises a semitransparent
green body containing an ink
dyeing assistant agent, and an ink jet penetrating layer penetrating into the semitransparent
green body. According to a preparation method, the ink
dyeing assistant agent is added into the semitransparent
green body, and ink jet penetrating technology is adopted, so that penetration of patterns into the semitransparent green body is realized,
polishing is carried out directly after
sintering, green
body surface particle flatness is excellent,
stain resistance is excellent, pattern
wear resistance is excellent, and requirements on highlight products are satisfied, adding of a transparent
glaze layer onto the surface of the green body is not necessary, cost is reduced, a problem that bonding of the
glaze layer with the green body is poor is solved, production deformation
cracking is avoided, the preparation method of the green body is simple, adding of non-transparent preform body is unnecessary, and in addition, the semitransparent green body contains the ink
dyeing assistant agent, so that the color of the patterns used for decoration is bright, sharpness is high, and decoration requirements can be satisfied preferably.
