Sintering of La0.88Sr0.12Ga0.82Mg0.18O2.85 ceramic | Elektrokhimicheskaya Energetika (Electrochemical Energetics)

The effect of both the molding pressure and the sintering conditions on a density of solid oxide electrolyte La_0.88Sr_0.12Ga_0.82Mg_0.18O_2.85 is studied. The ablation process of material components from ceramics surface to vaporous state at temperature up from 1573 К is observed. The lattice constant also changes at these conditions. It is assumed that phase transition exists that is responsible to these two phenomena.
