It can be seen from Figure 11 that the main compositions of the hollow-structured oxygen candle with r = 9 mm after combustion are halite (sodium chloride), hausmannite (manganese tetroxide),
manganosite (manganese oxide), and cobalt (II, III) oxide.
SAED intensity profile, plotted as a function of [d.sup.-1] ([nm.sup.-1]), of the sample Mn25 presents the typical peaks of both maghemite and jacobsite [28] and the presence of
manganosite and pyrolusite influences the symmetry of the peaks at 4.9 [nm.sup.-1] and 6.6 [nm.sup.-1] [28].
