- a semi-transmissive ceramic sheet having a light transmittance of 20% was obtained, and the decorative pattern on the surface was only the ink-jet decorative pattern of the step 7, and the decorative pattern of the step 6 was completely in the intermediate layer of the blank.
- Example 2 Basically the same as Example 1, except that the formula of the achromatic glaze is: ultra-white kaolin: 9, C30 soil: 12, quartz: 25, fused silica: 20, calcined talcum powder: 18, potassium feldspar powder: 22, bentonite 4, nano zinc oxide 2 .
- a semi-transmissive ceramic sheet having a light transmittance of 22% was obtained, and the decorative pattern on the surface was only the ink-jet decorative pattern of the step 7, and the decorative pattern of the step 6 was entirely in the intermediate layer of the green body.
- Example 2 Basically the same as Example 1, except that the formula of the green body is: ultra-white kaolin: 9, C30 soil: 12, quartz: 25, fused silica: 20, calcined talcum powder: 13, potassium feldspar powder: 22, bentonite 4 , W enhancer: 2, nano quartz 4.
- the formula of the green body is: ultra-white kaolin: 9, C30 soil: 12, quartz: 25, fused silica: 20, calcined talcum powder: 13, potassium feldspar powder: 22, bentonite 4 , W enhancer: 2, nano quartz 4.
- a semi-transmissive ceramic sheet having a light transmittance of 27% was obtained, and the decorative pattern on the surface was only the ink-jet decorative pattern of the step 7, and the decorative pattern of the step 6 was entirely in the intermediate layer of the blank.
- Example 2 Basically the same as Example 1, except that the thickness of the achromatic glaze layer was 0.05 mm. As a result, a semi-transmissive ceramic sheet having a transmittance of 21% was obtained, and the decorative pattern on the surface was only the ink-jet decorative pattern of the step 7, and the decorative pattern of the step 6 was completely in the intermediate layer of the blank.
- Example 2 Basically the same as Example 1, except that the thickness of the green body layer was 4.0 mm. As a result, a semi-transmissive ceramic sheet having a transmittance of 28% was obtained, and the decorative pattern on the surface was only the ink-jet decorative pattern of the step 7, and the decorative pattern of the step 6 was completely in the intermediate layer of the blank.
