Corrosion Of High Alumina And Near Stoichiometric Spinels

Feb 01, 2003 Dissolution of alumina-rich spinel aggregates in iron-containing silicate slag was studied using grain corrosion tests. High alumina spinels AR90, 90 Al 2 O 3 dissolve indirectly while dissolution of near stoichiometric AR78, 78 Al 2 O 3 spinel is entirely direct.This behaviour arises because higher alumina spinels can accommodate more cations from the slag due to the greater
