ZIRCONIA POWDER, METHOD FOR PRODUCING ZIRCONIA POWDER, METHOD FOR PRODUCING ZIRCONIA SINTERED BODY, AND ZIRCONIA SINTERED BODY
This zirconia powder contains 2.5 to 3.5 mol% of yttria; has a specific surface area of 5 to 20 m2/g; and has crystal phases that include a monoclinic crystal phase percentage of 20 to 40% and a tetragonal crystal phase percentage of 60 to 80%. When the zirconia powder is molded under a mold pressure of 0.8 t/cm2 and then sintered under a condition of 2 hours at 1450°C to obtain a sintered body, the sintered body has crystal phases that include a monoclinic crystal phase percentage of 1 to 3%, a tetragonal crystal phase percentage of 77 to 94%, and a cubic crystal phase percentage of 5 to 20%.
