Aluminum, alone and in several combinations with magnesium and silicon, has been evaluated as a corrosion inhibitor and slag modifier for heavy fuel ash. Stepwise linear regression analyses were carried out on the data and the results are compared with earlier data on magnesium and silicon. The Mg--Al--Si combination gives superior tolerance to aggravation of corrosion caused by sodium. It gives the slag a friability equivalent to Mg--Si combinations.
