Zirconia granularpowder for dental pre-sintered porcelain
Compared with traditional dental ceramics, tetragonal zirconia granulated powder (t-ZrO2) polycrystalline ceramics (Y-TZP) with yttrium oxide (Y2O3) as stabilizer has higher toughness due to the stress induced toughening of tetragonal zirconia to monoclinic zirconia (m- ZrO2). And has received the universal attention. Dental pre sintered zirconia granulation powder is an excellent high-tech biomaterial.
