本文介绍了在用Na·β-Al_2O_3为隔膜电解熔融NaOH制钠,和电解熔融NaCl(加ZnCl_2)制NaOH的试验中,Na·β-Al_2O_3被腐蚀的现象和影响腐蚀的因素,并对被腐蚀的原因进行了分析,初步探索了减轻腐蚀应具备的条件。
In this paper, Na · β-Al_2O_3 is corroded and the factors influencing corrosion are studied in the experiments of sodium ionization from Na · β-Al_2O_3 separator and NaOH from molten NaCl (plus ZnCl_2) The causes of corrosion were analyzed, and the conditions for mitigating corrosion should be preliminarily explored.
