Abstract
A housing for a portable electronic device is disclosed. The housing is composed of yttria-sensitized zirconia. Yttria-sensitized zirconia has from about 1.5 to about 2.5 mole percent yttria, and more typically about 2 mole percent yttria, and most typically 2 mole percent yttria, in zirconia. Yttria-sensitized zirconia is both tough and able to limit the formation and propagation of micro-cracks. Methods for manufacturing yttria-sensitized zirconia composed housings are also disclosed.
