THE EFFECT OF CTAB SURFACTANT ADDITION AND ADDITIONAL Sr ON PHASE FORMATION AND MAGNETIC PROPERTIES OF NANOSIZED SrFe12O19 SYNTHESIZED VIA SOL-GEL AUTO- COMBUSTION METHOD
trontium hexaferrite (SrFe 12 O 19 ) nanosized powders were synthesized by sol-gel auto-combustion method with and without cetyltrimethylammonium boromide (CTAB) addition in the sol with Fe/Sr ratio of 11 (using additional Sr). The resultant powders were investigated by X-ray Diffraction (XRD), Tran...

| description | trontium hexaferrite (SrFe
12
O
19
) nanosized powders were synthesized by sol-gel auto-combustion method
with and without cetyltrimethylammonium boromide (CTAB) addition in the sol with Fe/Sr ratio of 11 (using additional
Sr). The resultant powders were investigated by X-ray Diffraction (XRD), Transmission Electron Microscope (TEM),
Field Emission Scanning Electron Microscope (FESEM) and Vibration Sample Magnetometer (VSM) techniques.
Phase constituents of the synthesized samples which were heat treated at temperatures in the range of 700- 900 ◦C
were studied. XRD results revealed that CTAB addition facilitates the formation of single phase strontium hexaferrite
at 800 ◦C. Microstructural evaluations with FESEM represented that CTAB addition causes formation of larger
particles with a narrower size distribution. VSM results represented that the highest amount of intrinsic coercivity force
(
i
H
C
) was obtained in the sample without CTAB addition and with additional Sr, calcined at 800 ◦C for 1 h which was
equal to 5749.21 Oe, while the value of
i
H
C
was equal to 4950.89 Oe without additional Sr. The amount of maximum
magnetization (M
max
) was raised from 48.41 emu/g to 62.60 emu/g using CTAB and additional Sr. The microstructure
and magnetic properties of the samples have been explained |
