Abstract

The Strontium hexa ferrite with formula SrFe12O19 or SrO 6Fe2O3 is permanant magnet materials , it has high magnetic properties, high curie temperature (350oC) and good corrosion resistance. This research was done in preparation of Strontium hexa ferrite by using raw materials : hematite (Fe2O3) and SrCO3 at mole ratio SrO:Fe2O3 = 1 :6. The both raw materials were weighed and mixed by using HEM for 4 hours and aquadest as milling media. After that, the sample was dried at 110oC for 4 hours by using drying oven. The dried sample was analyzed by using DTA/TG to know the calcination temperature. According DTA/TG curve, there are 3 peaks endothermic at 730oC, 820oC and 990oC. After that , the sample was calcined at temperature 900oC and 1000oC for 2 hours. The calcined samples were analyzedcrystall structure by using XRD, measured magnetic properties by using VSM. According XRD results show that the first formation of SrFe12O19 phase at temperature 900oC, With the increasing of calcination temperature can increasing of SrFe12O19 phase. The VSM results show that it is obtained a wide hysteresis curve with highest coercivity value 3000Oe
