Answer» Themite process - It is a process in which molten metal oxides are treated with aluminium powder. It is highly exothermic reaction. The molten metal obtained is used for welding of railway tracks or cracked machine parts, eg., aluminium is heated with Fe2O3(haematite) to get molten iron and aluminium oxide2Al + Fe2O3 ---- 2Fe(molten iron) + Al2O3 + Heat Fe2O3 + Al = Al2O3 + Fe |
