Solid solution studies in the MgO-LiAlO2 system
- 67 Downloads
Experimental data in the MgO-LiAlO2 system indicates that about 53 wt % LiAlO2 can enter the MgO lattice in solid solution at 1600° C, an increase of 7,5 wt % over the solid solution phase at 1500° C. The data also indicates that the periclase lattice retains about 41% LiAlO2 at temperatures lower than 1400° C. Data indicates that there is probably no solid solution of MgO in LiAlO2. The proposed phase diagram for the MgO-LiAlO2 system is presented with an estimated eutectic composition of 17 wt % MgO-83 wt % LiAlO2 and a melting point of ∼ 1625° C.
