Hot pressing of stoichiometric Al2O3-MgO powder mixtures has been preferred to the direct pressing of spinel powder for the readily availability of pure powders and to exploit the thermodynamic driving force of the spinel formation. LiF has been used as sintering additive.
Hot pressing has been investigated for the production of transparent MgAl2O4 aimed at the scaling up of the process. Other assessed techniques (hot isostatic pressing, spark plasma sintering) can hardly be used for the production of flat components with large dimensions and good planarity.

Abstract
Hot pressing has been investigated for the production of transparent MgAl2O4 aimed at the scaling up of the process. Other assessed techniques (hot isostatic pressing, spark plasma sintering) can hardly be used for the production of flat components with large dimensions and good planarity.File in questo prodotto:
