Determinación de los números de transporte iónico de materiales basados en el galato de lantano mediante técnicas de espectroscopia de impedancia y FEM

“…3 and 4. The cell parameters and space groups of these compositions are summarised in Table I, and they are in accord with the literature (18). It should be noted that an increase …”

Low temperature thermoelastic and structural properties of LaGaO3 perovskite in the Pbnm phase

“…The first order structural phase transition in LaGaO 3 , from orthorhombic Pbnm (Pnma in standard setting) to rhombohedral F32=n (R3c in standard setting) has been the subject of numerous studies in recent years [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. We make this choice of the rhombohedral space group setting as it allows ease of comparison with both the aristotype and hettotype phases of perovskitestructured phases that is not immediately apparent from the more commonly used primitive rhombohedral, or triply-primitive hexagonal settings.…”

Electrochemical Investigation of LSGMC-Composite Cathodes on LSGM-Substrate

“…XRD patterns have been identified as the desired perovskite phase with the cubic structure (space group Pm3m) for LSGM (23,24) and LSGMC (25). The secondary phases of LaSrGa 3 O 7 (JCPDS # 45-0637) and LaSrGaO 4 (# 80-1806) were present in both LSGM and LSGMC samples at the low calcination temperature.…”

“…The secondary phases of LaSrGa 3 O 7 (JCPDS # 45-0637) and LaSrGaO 4 (# 80-1806) were present in both LSGM and LSGMC samples at the low calcination temperature. Both LaSrGa 3 O 7 and LaSrGaO 4 have been reported as minor phases during the synthesis of LSGM (24,26) and of LSGMC (27). Neither of the secondary phases is desirable.…”
