In order to improve MnO2 electrochemical properties, various manganese dioxide composite materials have been studied, MnO2/C composite material is a hot topic of current research.
MnO2/C composite materials can be prepared by many ways, such as chemical precipitation, hydrothermal synthesis method, the oxidation-reduction method, microwave method and electrochemical method[4-7].
Materials and Methods 2.1 Chemicals All chemicals used in this study were of analytical grade.

If the magnetic field intensity is increased, it could provide better performance of raw materials to cold rolling processing.
Domestic materials science scholars published papers since 2002[11-13], they studied the effect of strong magnetic-field annealing on recrystallization texture of cold-rolled IF steel sheet and got the results that the higher magnetic field strength, the bigger ferrite content and grain.
Experimental Materials and Methods The test material are taken from SPHC thin slab rolling coil of a steel company.

Enhancing the engine performance via increasing the operating temperature reveals a need to materials with lower thermal conductivity and sinter-ability.
This means that selected oxides for new TBC materials should have better compatibility with Al2O3.
