Abstract: A ceramic material includes zirconia toughened alumina (ZTA) doped with scandium (Sc) ions. ZTA can be further doped with other metal ions, and the other metal ions include cobalt (Co) ions, chromium (Cr) ions, zinc (Zn) ions, titanium (Ti) ions, manganese (Mn) ions, nickel (Ni) ions, or a combination thereof. The ceramic material can be used as a ceramic object, such as a wire bonding capillary, a heat dissipation plate, a denture tooth, orthopedic implants, direct bonded copper, or a high-temperature co-fired ceramic.

Abstract: Disclosed is a method of manufacturing a ceramic powder, which includes forming a slurry by mixing of first ceramic particles, binder and water, spraying and drying the slurry to form a first ceramic core portion, and thermally treating and shaping the first ceramic core portion. The first ceramic core portion has a first flexural strength and a first coefficient of thermal expansion. The method further includes forming another slurry to form a second ceramic shell portion formed by second ceramic particles and covering the first ceramic core portion. The second ceramic shell portion has a second flexural strength and a second coefficient of thermal expansion. The ceramic powder is formed by thermally treating and shaping the first ceramic core portion and the second ceramic shell portion.
