www.ijert.orgReaction result between high temp liquid aluminum and air in melting is formation of oxides. Thermite reaction causes the dross. Higher the temperature of metal. 3.6.2 Remedies Lower the reaction time which reduces the formation of dross. Avoid the stirring which causes the thermite reaction and oxidation.

users.stlcc.edu5.69 The following is known as the thermite reaction 2 Al (s) + Fe 2O 3 (s) Al 2O 3 (s) + 2 Fe (s) This highly exothermic reaction is used for welding massive units, such as propellers for large ships. Using standard enthalpies of formation in Appendix C, calculate ΔH° for this reaction. Use Enthalpy of Formation data and equation:
