Abstract:
A zirconia ceramic material for use in dental applications is provided comprising an yttria-stabilized zirconia material comprising from 4.5 mol % to 5.1 mol % yttria. Optionally, the zirconia ceramic has a coloring agent that may comprise one or more metals selected from terbium (Tb), chromium (Cr), erbium (Er), and cobalt (Co), and further, may, optionally, comprise alumina, which if present may be in an amount from 0 wt % to 0.25 wt %. The zirconia ceramic materials exhibit both enhanced translucency and a flexural strength of at least 800 MPa when fully sintered.

Claim (Index 7):
The shaded ceramic zirconia material of  claim 2 , wherein the coloring agent comprises at least one metal selected from:\n a. Tb, measured as Tb 4 O 7 , in an amount from 0.03 wt % to 0.06 wt %; b. Cr, measured as Cr 2 O 3 , in an amount from 0.001 wt % to 0.0025 wt %; c. Er, measured as Er 2 O 3 , in an amount from 0.02 wt % to 0.6 wt %; and d. Co, measured as Co 3 O 4 , in an amount from 0.00008 wt % to 0.0045 wt %.
