Mixed oxides have a widespread application as magnets, catalysts, and ceramics. Often, nonstoichiometric mixtures with unusual properties can be prepared for example, Fe203 and ZnO have been milled for the production of zinc ferrite [40], while mixed oxides of Ca(OH)2 and Si02 were described by Kosova et al. [77]. Piezoceramic material such as BaTi03 from BaO and anatase Ti02 has been prepared [78], while ZnO and Cr203 have been treated by Marinkovic et al. [79] and calcium silicate hydrates from calcium hydroxide and silica gel by Saito et al. [80]. The thermal dehy-droxylation of Ni(OH)2 to NiO or NiO-Ni(OH)2 nanocomposites has also been investigated [81].

Because the transition rate between the ortho- and para- states is low except in the presence of magnetic catalysts, we can equilibrate the gas at a given temperature in the presence of a magnetic catalyst. For low temperatures, in the presence of a catalyst, the system will become virtually entirely para while for high temperatures it will tend to 25% para and 75% ortho. We can therefore do neutron scattering experiments with different predetermined ratios of the two forms so that both cross-sections can be extracted. 

The Congo, Zambia, Canada, Morocco, and New Caledonia are considaed the main places of production of the cobalt ore. The main use of the cobalt ore was for aircraft superalloys, hard metal tools, magnets, catalysts, and pigments before the rechargeable lithium-ion battery was developed. Therefore, the cobalt oxide that could be used for batteries was low. However, the number of manufacturers producing the cobalt oxide recently has increased due to the expansion of the market In our company, various cobalt raw materials produced by 6-7 companies are always being evaluated.
