Study on the effect of the effect of different raw materials sources on spinelization and densification of MgO-Al2O3 spinel

Abstract

In our work study is done on the effect of spinelization using different commercially available raw materials of magnesia and alumina. In the study 16-SG, and CL-370 grade of alumina used, and fused magnesia, Netherland magnesia and chemical grade magnesia are used. The spinelization is done using solid state reaction of stoichiometry magnesia and alumina ratio. All the possible combustion of magnesia and alumina are used, which formed 6 batches. These batches are palletized and fired at and fired at 5 different temperature of 1200oC, 1300oC, 1400oC, 1500oC, and 1600C. The samples are taken for XRD analysis and dilatometer test of the sample determine the off set of sintering and formation of spinelization temperature. The bulk density of the sample is determined. For determining microstructure of spinel SEM of fractured surface is done. And all the experimental data has been studied and correlated with each other.
