Reasons for cracks in zirconia ceramic parts

Release time：2024-09-11click：1

Under what circumstances will cracks occur in zirconia ceramic parts?

1. Caused by the fineness modulus of zirconia ceramic sand being too fine and the mud content being too high;

2. Due to uneven mixing of zirconia ceramic mortar, stress caused by inconsistent shrinkage leads to cracks in the protective layer;

3. The proportion of cement in the zirconia ceramic mortar is too large and the number is too high, causing the mortar to shrink too much and too fast in the early stage;

4. The water absorption rate of the zirconia ceramic protective layer mortar is too high, causing cracks due to frost heaving in winter;

5. Due to the insufficient flexibility index and low elongation of zirconia ceramic adhesive, the surface layer glueReduced resistance to deformation.
