Microstructure refinement of alumina Optimisation by gas pressure sintering process

Abstract

This paper investigates densification and grain growth evolutions during gas pressure sintering of alumina. Isothermal sintering runs are performed under different nitrogen pressures: atmospheric pressure and 2 MPa. Experimental data are fitted thanks to constitutive laws in order to understand nitrogen pressure effect on densification and grain growth mechanisms of a fine-grained alumina. An optimal run of densification is proposed as an application of these results. (C) 2007 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
