Fused yttria stabilized zirconia / ytterbium stabilized zirconia

Using different grades of zirconia raw materials, adding varying doses of yttrium oxide and different doses of ytterbium and gadolinium oxides, different types of electric melting yttrium, ytterbium, and gadolinium are produced using special electric melting processes. The stable zirconia raw materials come in two forms: hollow spheres and solid particles, with the product's crystal phase composition being monoclinic and cubic. It can be made into crushed graded powder for plasma spraying.
