8YSZ sintering by flash sintering method and evaluation of process parameters

Flash sintering as a new sintering method for sintering of ceramic materials has been studied and effect of various parameter such as flash current density, time of flash and contact paste on properties of flash sintered 8YSZ samples has been investigated. Results showed it is possible to achieve high density in shorter time and lower temperature than conventional sintering methods. Samples cou...

Macrochanneled Tetragonal Zirconia Polycrystals Coated by a Calcium Phosphate Layer

A coextrusion process was used to fabricate three-directionally macrochanneled tetragonal zirconia polycrystals (TZP) with a calcium phosphate coating layer. The three-directionally connected structure was built by a unique alignment and a lamination of the TZP surrounded by calcium phosphate and carbon black filaments. After a thermal treatment (binder burnout and sintering), a 52 vol% array o...
