Influence of Additives of Aluminum, Magnesium and Calcium on Synthesis and Sintering of Lanthanum Chromite

摘要

In this paper, materials based on lanthanum chromite La_(1-x)A_xCr_((1-y))B_yO_3 doped with Ca in the A position and Al and Mg in the B position are obtained. The influence of the introduced additives on the particle size, morphology, and phase composition of powders and properties of sintered ceramic samples based on lanthanum chromite is studied. It is established that the additive of magnesium in the amount of 20 mol % promotes the best sintering of ceramics and level of properties compared to other compositions studied in this work.
