Table 7.1
Metal molar fractions for samples discussed in the text. For
samples A 7 , A 7 ’ and B 7 , all heated in oxygen, the composition is
as-dispensed, while for C 7 –G 7 , heated in air, the compositions
shown were obtained with elemental analysis for the regular
cooled samples. The values for the M, N, R and S samples are
for synthesis in oxygen from Chaps. 5 and 6 ......................

Metal molar fractions for samples A 8 –D 8 and Li 2 MnO 3
discussed in this chapter. For Li 2 MnO 3 the expected
composition is shown, while for A 8 –D 8 the actual compositions
obtained by elemental analysis are shown.......................... 111
