Problems of potassium cryolite low temperature electrolyte

   In addition, in the process of low-temperature electrolysis, K+ is enriched at the cathode, and the electrolyte molecule ratio near the cathode increases, resulting in the phenomenon of cathode encrustation. The common phenomenon in the electrolysis process with potassium cryolite as the electrolyte is that the cell voltage is high and fluctuates greatly, and the current efficiency is low. Potassium cryolite molten salt corrodes the inert anode and side liner materials more seriously, and it is necessary to further search for suitable inert anode and side liner materials.
