摘要： The invention relates to a method for preparing a substantially lead-free turbulence promoting electrode, wherein an amount of turbulence promoting particles having a particle size from about 30 to about 2000 nullm are contacted with at least one electrode and brought to adhere thereto, such that from about 5 to about 50% of the projected electrode surface area is covered with the particles. The invention also relates to a turbulence promoting electrode obtainable by the method and an electrode comprising turbulence promoting elevated parts arranged on at least one surface of the electrode. The height of the elevated parts is from about 30 to about 2000 nullm. The invention further relates to the use of the electrode in an electrolytic cell for the production of alkali metal chlorate and alkali metal hydroxide.
