Methods of manufacture of electrolyte tubes for solid oxide devices and the devices obtained therefrom

摘要

A method of manufacturing a green electrolyte tube comprises forming a composition comprising lanthanum-strontium-gallium-magnesium oxide powder, a binder, a lubricant, a solvent and a pH control agent into a green electrolyte tube, wherein the outer diameter of the green electrolyte tube has a tolerance of less than or equal to about ±0.3 millimeters over a tube length of greater than or equal to about 5 millimeters, and the wall thickness of the green electrolyte tube has a tolerance of less than or equal to about ±0.2 millimeters over a length of greater than or equal to about 5 millimeters.
