An electrochemical sodium sensor for aluminium melts

摘要: Abstract The modification of aluminium-silicon alloys by sodium addition before casting results in an improvement the mechanical properties alloy. As has a high reactivity with air, it forms oxide or hydroxide vapours and total amount alloy decreases as function time. This paper describes development test electrochemical sensor for determination aluminum-silicon described experiments show promising features such aluminum industry, where level must be held between 50 200 ppm
