Phase Equilibria in the LaAlO_3-LaSrAlO_4 System

摘要

The phase equilibria are investigated and the phase diagram is constructed for the LaAlO_3-LaSrAlO_4 pseudobinary join of the La_2O_3-SrO-Al_2O_3 ternary oxide system.One ternary compound,namely,La_2SrAl_2O_7,is found in the LaAlO_3-LaSrAlO_4 join.The crystallographic,thermal,and some other physico-chemical characteristics of the compounds are reported.
