Use of High Silicon Cast Iron for Anodes

Abstract

Abstract Data are tabulated from questionnaire replies received from more than 100 companies pertaining to use of high silicon cast iron for anodes. Of the 230 installations for which data were reported, 53 percent concerned ground bed applications, 37 percent fresh water and 10 percent salt water. In general, data indicate high silicon cast iron anodes are at least equal to graphite anodes in ground bed applications where coke breeze backfill is utilized and superior in marshland and other areas where backfill is impractical. In fresh water applications high silicon cast iron anodes perform very well so long as the temperature does not exceed 125 F. At high temperatures the molybdenum containing alloy is preferred as is also the case in many brackish or salt water applications where the temperature may exceed 100 F. 6.2.2
