Many other metal oxides and metals can be used for thermite. Some metals that can be used are boron, magnesium, calcium, titanium, zinc, or silicon. Some metal oxides that can be used are copper(II) oxide, chromium(III) oxide, iron(II,III) oxide, manganese(IV) oxide, silicon dioxide, boron trioxide, or lead(II,IV) oxide. A metal cannot be used with its metal oxide. The metal has to be more reactive than the metal in the oxide, or the thermite will not work.
