Claim Text:
1. A method for manufacturing a ceramic biomedical implant, the method comprising the steps of: preparing a first feedstock by mixing ingredients comprising at least aluminum oxide and strontium carbonate or ingredients selected to yield aluminum oxide and strontium carbonate; preparing a second feedstock by mixing ingredients comprising at least aluminum oxide and calcium carbonate or ingredients selected to yield aluminum oxide and calcium carbonate; preparing a slurry comprising materials from the first feedstock, materials from the second feedstock, and further comprising additional ingredients configured to yield at least a portion of a ceramic biomedical implant comprising at least aluminum oxide, zirconium dioxide, yttrium oxide, cerium oxide, strontium oxide, magnesium oxide, titanium dioxide, and calcium oxide; forming a compact derived from the slurry; firing the compact to obtain a fired piece; after the step of firing the slurry, compressing the fired piece; and reoxidizing the fired piece, wherein, following the step of reoxidizing the fired piece, the fired piece comprises at least aluminum oxide, zirconium dioxide, yttrium oxide, cerium oxide, strontium oxide, magnesium oxide, titanium dioxide, and calcium oxide, and wherein the fired piece comprises a combination of aluminum oxide, strontium oxide, magnesium oxide, titanium dioxide, and calcium oxide in a concentration of at least about 84% by volume.
