What is Chlorate Electrolyzer
Chlorate Electrolyzer is mostly used to prepare low-melting-point metals. It is characterized by operating at high temperatures and should try to prevent the entry of moisture to prevent hydrogen ions from being reduced on the cathode. For example, in the production of metallic sodium, since the cathode reduction potential of sodium ions is very negative, reduction is very difficult. Anhydrous molten salt or molten hydroxide containing no hydrogen ions must be used to avoid hydrogen precipitation at the cathode. For this reason, the Chlorate Electrolyzer electrolysis process needs to be carried out at a high temperature. For example, the electrolysis temperature is 310°C when the sodium hydroxide is electrolyzed. If sodium chloride is included as a mixed electrolyte, the electrolysis temperature is about 650°C.
The high temperature of Chlorate Electrolyzer can be achieved by changing the electrode spacing to convert the electrical energy consumed by the ohmic voltage drop into heat energy. When electrolyzing molten sodium hydroxide, the tank body can be iron or nickel. The electrolysis of molten electrolyte containing chloride is often due to the inevitable introduction of a small amount of moisture in the raw material, which will cause the anode to generate moist chlorine gas, which has a strong corrosive effect on the Chlorate Electrolyzer. Chlorate Electrolyzer generally uses ceramic or phosphate materials, and iron can be used for parts that are not affected by chlorine.
The cathode and anode products in the Chlorate Electrolyzer also require proper separation and should be drawn out from the tank as soon as possible to prevent the cathode product metal sodium from floating on the surface of the electrolyte for a long time, which will further interact with the anode product or oxygen in the air.
