Preparation method of functionally graded zirconia ceramic material with dental glass part permeation
The invention discloses a preparation method of a functionally graded zirconia ceramic material of with dental glass part permeation. The preparation method comprises the specific steps: firstly preparing permeation glass with good wettability and good biology consistency, then pressing zirconia powder to green body by adopting a cold pressing molding method to be presintered to prepare a multihole presintered zirconia material, and finally permeating a glass sizing agent on the surface of multihole zirconia for dense sintering through capillary permeation technology. By utilizing the preparation method, under 1350 DEG C, glass permeation is carried out on zirconia by utilizing the capillary permeation technology, the wettable performances of permeation glass and zirconia are good, mutually blended compact structure is formed, zirconia does not have phase change, and sintering shrinkage rate is not increased significantly.
