EPR Study of Fe3+- and Ni2+-Doped Macroporous CaSiO3 Ceramics

Abstract.  Thermally stable macroporous CaSiO3, Fe3+- and Ni2+-doped (0.5 to 5 mol%) ceramics have been prepared by solution combustion process by mixing respective metal nitrates (oxidizers), fumed silica. Diformol hydrazine is used as
