Abstract

The invention relates to a high-strength semitransparent ceramic sheet and a preparation method for the high-strength semitransparent ceramic sheet. The high-strength semitransparent ceramic sheet is prepared by sintering the formula components: 20-25% of sodium sand, 15-20% of potassium feldspar, 9-13% of high potassium sand, 20-25% of potassium sodium feldspar, 1-3% of barium carbonate, 12-15% of calcined kaolin, 5-15% of bone meal, and 1-3% of sheet aluminum oxide in percentage by weight at high temperature. The preparation method comprises the following steps: (1) preparing powder; (2) forming by punching; (3) drying and sintering; (4) polishing to make the high-strength semitransparent ceramic sheet. Sheet aluminum oxide particles are added in an original semitransparent ceramic material, an inorganic peroxide crystal whisker is further added, the water absorption of the semitransparent ceramic material is reduced, the breaking strength is improved, and then the semitransparent ceramic material is applied in the ceramic sheet, so that the water absorption of the ceramic sheet is reduced, and the breaking strength of the ceramic sheet is improved.
