Hydrous manganese oxide是什么
http://www.minsocam.org/ammin/AM77/AM77_1133.pdf Webmanganese oxides at 600 °C were Mn2O3 (bixbyite-C, JCPDS 41-1442), and the samples calcined at 1000 °C was Mn3O4 with a minor phase of Mn2O3, as shown in Fig. 1. Surface area of the powders is a function of H2O2. Surface areas of amorphous manganese oxide (CMP01) and Mn3O4 (CMP06) were 100.1 and 23.4 m 2/g, respec-tively.
