The Influence of Starting Mass Grain Size Distribution on Magnesia-Spinel Products Microstructure
The paper presents the results of investigations on the influence of the starting mass grain size distribution on microstructure of sintered magnesia-spinel products. The model investigation was conducted using magnesia clinkers and fused spinel. The grain size distribution of starting mixes were selected according to Dinger and Funk's theoretical curves with different values of n coefficient. The results clearly indicate that the best properties were achieved when n value changed in the range of 0.22 - 0.30 and forming pressure was contained in the range of 160 - 200 MPa.
