Abstract:
1. A partially sintered body comprising a product formed by partially sintering zirconia-based particles that are crystalline, that have an average primary particle size no greater than 100 nanometers, and that comprise a) at least 92.5 mole percent zirconium oxide based on total moles of inorganic oxide in the zirconia-based particles; b) at least 0.5 mole percent lanthanum oxide based on total moles of inorganic oxide in the zirconia-based particles; c) at least 1.5 mole percent yttrium oxide based on total moles of inorganic oxide in the zirconia-based particles, wherein the partially sintered body comprises 25 to 75 volume percent inorganic oxide and 25 to 75 volume percent voids based on a total volume of the partially sintered body.
