Iron oxide powder combined with aluminium powder forms a mixture called thermite. When ignited, thermite produces aluminium oxide and molten iron in a highly exothermic reaction. Thermite reactions are extremely hazardous unless appropriate precautions are taken. link title Headline text Bold textItalic textItalic textInsert non-formatted text hereInsert non-formatted text hereInsert non-formatted text hereInsert non-formatted text hereInsert non-formatted text here--220. ...
