Abstract

The method comprises the steps of preparing a solution of a binder in a solvent, wetting and grinding polyantimonic powder, forming a suspension with the wetted and ground powder and the solvent, mixing the suspension with the solution, pouring on a plate the so obtained viscous liquid, allowing the solvent to evaporate until a membrane in formation begins to dry, removing further the solvent by lixiviation, and removing the membrane from the plate.
