Solution combustion synthesis of nanocrystalline Fe–50%Ni alloy powder

Various nanocrystalline metal alloy powders were synthesized by solution combustion synthesis in a reducing atmosphere in which a spray pyrolysis process was modified. Miscible Cu–Ni alloy powder and immiscible Ag–Ni alloy powder were synthesized, along with Cu–Y2O3 metal-ceramic composite powder. X-ray diffraction, SEM and TEM observations showed that the synthesized powders were nanocrystalline and well alloyed. Alloying occurred via the chemical routes of the decomposition of the metal salts, as well as the oxidation, reduction and sintering processes.

Liquid Combustion

Effect of nitric acid and the burning time on the liquid combustion synthesis of spinel LiMn2O4 has been studied, using lithium nitrite and Manganese acetate as raw a material. The results show that the main phases are all LiMn2O4, which can be obtained at 400-600 oC. Before modified, the impurity is Mn3O4 or Mn2O3. After modified, the impurity is only Mn3O4. The aggregation obviously reduced after adding nitric acid, it is indicated that the crystalline increased. With the increasing temperatures, the modified particle size was increased and the aggregation reduced. The initial discharge capacity and cycle stability improved at some extent too. Its first discharge capacity was 104.6, 112.8 and 117.7mAh/g synthesized at 400, 500, 600 oC, respectively, and the 30th capacity retention rate were 84.89%, 80.67% and 73.24%.
