Description
Summary:Low temperature synthesis of spinel powder via intense mechanical grinding was performed. A dramatic decrease in the synthesis temperatures of ground powders was achieved. We were able to produce partially crystallized spinel at room temperature via a 110 minute grinding. Characterization of the synthesized powders was performed using SEM, XRD and DTA. Each stage of synthesis was analyzed using these techniques. Mixtures of Mg(OH)2 and Al(OH)3 were used for synthesis. Temperatures as low as 800 deg C were able to produce bumps in the XRD patterns of ground powders at the 20 angles for spinel crystals.
