Abstract

Хлорат натрия производится промышленно с помощью электролиза солевого раствора и поэтому является энергоемким процессом. Усовершенствованный катод для этого и других промышленных процессов представляет собой нержавеющую сталь с низким содержанием никеля, поверхность которой надлежащим образом изменена. С помощью соответствующей степени поверхностной шероховатости катод обеспечивает улучшенные перенапряжения во время электролиза, одновременно сохраняя стойкость к коррозии.Sodium chlorate is produced industrially by electrolysis of a saline solution and therefore is an energy-intensive process. The improved cathode for this and other industrial processes is stainless steel with a low nickel content, the surface of which is properly modified. Using an appropriate degree of surface roughness, the cathode provides improved overvoltage during electrolysis, while maintaining corrosion resistance.
