Abstract
A ceramic material includes zirconia toughened alumina (ZTA), which is doped with zinc ions and other metal ions, in which the other metal ions are chromium (Cr) ions, titanium (Ti) ions, gadolinium (Gd) ions, manganese (Mn) ions, cobalt (Co) ions, iron (Fe) ions, or a combination thereof. The ceramic material may have a hardness of 1600 Hv10 to 2200 Hv10 and a bending strength of 600 MPa to 645 MPa. The ceramic material can be used as wire bonding capillary.
