The Formation of Cr-Al Spinel under a Reductive Atmosphere.

In the present work, for the first time, the possibility of formation of CrAlO was shown from the equimolar mixture of co-precipitated AlO and CrO oxides under a reductive environment. The crystallographic properties of the formed compound were calculated using the DICVOL procedure. It was determined that it has a cubic crystal structure with space group Fd-3m and a unit cell parameter equal to 8.
