For decades in diaphragm electrolysis, asbestos containing diaphragms have been utilized to separate the anode and cathode compartments. Due to the harmful characteristics of asbestos, its world‐wide prohibition in diaphragm manufacturing is expected. The objective of this work was focussed on the development of a diaphragm with sufficient mechanical and chemical stability to substitute the modified asbestos diaphragm currently used. Suitable materials for the manufacture of non‐asbestos diaphragms were identified and a deposition technology was developed which fulfils the requirements of industrial production plants.
