The invention discloses yttrium-stabilized zirconia and a production process thereof, and belongs to the technical field of zirconia materials. The production process of the yttrium-stabilized zirconia comprises the following steps: 1) uniformly mixing preparation raw materials, and keeping the temperature at 2600 to 2800 DEG C for 1-3h to prepare a molten liquid, wherein the preparation raw materials comprise the following components in parts by weight: 88-92 parts of zirconium oxide, 8-10 parts of yttrium oxide, 0.8-1.5 parts of calcium oxide and 0.2-0.3 part of magnesium oxide; and 2) blowing the molten liquid obtained in the step 1) by adopting compressed gas, and cooling the blown particles. The yttrium-stabilized zirconia production process disclosed by the invention adopts a very high sintering temperature, so that the zirconia material with high density and uniform crystalline phase distribution can be prepared; the material has high stability and cracks are not easy to occur on the surfaces of the particles.
