New strontium iron(II) orthophosphates, SrFe 2 (PO 4 ) 2 and Sr 9 Fe 1.5 (PO 4 ) 7 , were synthesized by the solid state method at 1170 K. They were characterized by X-ray powder di4raction, thermal analysis in air, magnetic susceptibility, and the IR and MoK ssbauer spectroscopy methods. MoK ssbaue
Five phosphates, Sr 9 A(PO 4 ) 7 (A=Sc, Cr, Fe, Ga, and In), were synthesized by the solid state method at (1270 to 1420) K and characterized by X-ray powder diffraction, infrared spectroscopy, differential scanning calorimetry, thermogravimetry, and second-harmonic generation (SHG). SHG showed Sr 9
