Abstract:Hollow yttria-stabilized zirconia (YSZ) microspheres with a diameter of 1.2-5.1 μm and a wall thickness of about 125 nm were synthesized, and their thermal stability was revealed for a hold time of 1 h at temperatures of 800°C, 1000°C and 1200°C. The microspheres were then used as raw materials to prepare bulk porous ceramics by gelcasting processing. The effects of the solid loading contents and sintering temperatures of the hollow YSZ microspheres on the microstructures, porosity, compressive strength and ro… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
