Process for Improving Flash Sintering of Ceramics and Improved Ceramics

Methods of flash sintering have been developed in which particle are initially coated with thin layers by atomic layer deposition (ALD). Examples are provided in which 8 mol % yttria-stabilized zirconia (8YSZ) particles are coated with small quantities of Al2O3 by particle atomic layer deposition (A...

Beschreibung
Zusammenfassung:	Methods of flash sintering have been developed in which particle are initially coated with thin layers by atomic layer deposition (ALD). Examples are provided in which 8 mol % yttria-stabilized zirconia (8YSZ) particles are coated with small quantities of Al2O3 by particle atomic layer deposition (ALD). Sintered materials that result from the process have been characterized. Sintered materials having unique characteristics are also described.
