Freeze‐cast porous alumina tubes for membrane applications: Role of niobium pentoxide in microstructure and gas transport properties Open
This study investigates the porosity, microstructure, mechanical strength, and gas permeation behavior of high‐purity α‐Al 2 O 3 tubes doped with 0.25‒5.0 wt.% of monoclinic or amorphous Nb 2 O 5 , fabricated via freeze‐casting and pressur…
