Ternary chromites of the composition LaM I Mg(CrO 3 ) 2 (M I = Li, Na, K) were synthesized for the first time by ceramic technology from stoichiometric amounts of high purity grade La 2 O 3 ; pure for analysis grade Li 2 CO 3 , Na 2 CO 3 , K 2 CO 3 , and MgCO 3 ; and chemically pure grade Cr 2 O 3 . Using X-ray diffractometry, it has been established that compounds are crystallized in cubic and tetragonal crystal systems, and parameters of their crystal lattices have been determined.
