Abstract
The present disclosure belongs to the field of biological materials, and particularly relates to a multilayer zirconia ceramic with uniform transition and a method for preparing the same. The specific technical solution of the present disclosure is as follows: a zirconia ceramic with a formula comprising, in percentage by mass, 0-3% of lanthana, 1.5-16% of yttria, 0-2.5% of silicon carbide nano-whiskers, and 0-1.5% of a coloring agent, the balance being zirconia. Correspondingly provided are a multi-layer zirconia ceramic with uniform transition prepared using the formula and a method for preparing the same. By using the method of the present disclosure, multilayer zirconia ceramics with good and uniformly transitioning core properties can be quickly and conveniently prepared, meeting the requirements of patients with dental disorders on the use and esthetics of dentures.
