Abstract
Ceramic materials comprising charge-compensating dopants and related methods. In some embodiments, the materials may comprise dopants such as Y2O3, Gd2O3, Nb2O5, and/or Ta2O5. Some embodiments may comprise a molar concentration of Y2O3 and/or Gd2O3 that is at least approximately equal to the molar concentration of Nb2O5 and/or Ta2O5. Certain embodiments and implementations may comprise particular, unique concentrations or concentration ranges of various compounds/materials in order to improve performance for use of such ceramic materials as biomedical implants.
