Mechanism of the formation of novel Al2-xHfxO3 materials via a combustion synthesis method

In this paper, the synthesis mechanism of novel hafnium-doped alumina, Al2-xHfxO3 (x = 0.001, 0.002 and 0.003) materials have been successfully formed via a self-propagating combustion (SPC) method. In-depth study of the materials through characterization by simultaneous thermogravimetric analysis...
