Solution
The reduction of metal oxides by aluminium powder is called Gold schmidt's aluminodiermite process.
$\mathop {\mathop {C{r_2}{O_3}}\limits_{(3\,\,part)} + \,\mathop {Al\,powder}\limits_{(1\,part)} }\limits_{{\text{Thermite mixture}}} \,\xrightarrow[{ignition\,\,mixture}]{{Mg\,powder\, + \,Ba{O_2}}}\mathop {2Cr}\limits_{(Mohen)} + A{l_2}{O_3} + Heat$
