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.
Claims3
A method of preparing a membrane consisting of polyantimonic acid powder and an organic binder, comprising the steps of
- preparing a solution of the binder in a solvent,
- wetting the polyantimonic powder with the same solvent,
- grinding the wetted powder,
- forming a suspension with the wetted and ground powder and a same 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 process of formation begins to dry,
- removing further the solvent by lixiviation, and
- removing the membrane from the plate.
