METHOD FOR CORROSION PROTECTION OF EQUIPMENT OPERATING IN MOLTEN POTASSIUM CHLOROALUMINATE MEDIUM

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to a method for corrosion protection of equipment operating in a molten potassium chloroaluminate medium. The method includes removing impurities form the melt at the preparation step thereof using aluminium metal containing not less than 99.95 wt % aluminium with weight ratio of aluminium to the obtained melt of 1:25-30. The aluminium metal is attached to the surfaces of the equipment in contact with the melt while allowing electrical contact, with the ratio of the area of the protected equipment and the aluminium metal of not less than 10:1.;EFFECT: high degree of corrosion protection of equipment, components thereof and elements for using molten potassium chloroaluminate.;4 dwg, 2 tbl
