Densification of magnesium aluminate spinel was studied with both the single stage and double stage sintering processes using attritor mill for the reduction of particle size. Presynthesized spinel and a stoichiometric mixture of calcined magnesia and alumina were used for the study. Presynthesization of spinel and calcination of raw materials were done at 1400 and 1600 degrees C. Milling was done for 2, 4 and 6 h. Extent of milling was characterised by measuring the specific surface area of the milled powders. Densification was found to be greatly influenced by milling. A maximum 99.5% densification was obtained. (C) 1999 Elsevier Science Limited and Techna S.r.l. All rights reserved.
