3 Terms and Definitions

The following terms and definitions apply to this document. 3.1 Fused zirconia is zircon sand (formula. ZrSiO4) main raw material, carbon material as a reducing agent in an electric arc furnace in the reduction of zircon sand Desilication by blowing or casting off after generating zirconium silicon, it is also referred to as silica zirconium or fused silica zirconium. 3.2 Stabilization rate rateofstabilizion Fused zirconia into monoclinic polymorph according to phase (mZ), tetragonal (tZ), cubic phase (cZ), in which the tetragonal phase, the cubic phase is stable. The stability of fused zirconia in order to stabilize the rate, said. Stabilization rate (%) = [(cubic tetragonal phase)/(cubic tetragonal monoclinic)] × 100

4 Classification and designation

4.1 Classification Fused zirconia into monoclinic and partially stabilized type two categories. Zirconia partially stabilized by the stabilizer used is divided into type calcium (Ca yttrium complex) stabilized zirconia, magnesium (Mg composite yttrium) oxide stabilized Zirconia, yttria-stabilized zirconia and the like. Grade 4.2 Grades from English letters and numbers. Z is the English "zirconia" prefix, P is the English "partial" prefix, C, M, Y, respectively ......
