Metallic Aluminum and Dry Ice We see $\ce{2Mg + CO2 -&gt; 2MgO + C}$ , quite often in lab experiments. 

Under which conditions can $\ce{4Al + 3CO2-&gt; 2Al2O3 + 3C}$ be used - if chemically feasible?
Based on this (very old) paper - http://link.springer.com/article/10.1007%2FBF00740367#page-1 - the aluminum will ignite if you heat it past the melting point of aluminum oxide, 2060C.
