Abstract
This experiment was carried out to investigate the new process of the preparation of fine particles of SrO⋅6Fe2O3 with single phase by controlling the chemical coprecipitation(a solution containing Fe3+ and Sr2+ in the ratio 10.0-12.0) and succeeding heat treatment. The new process is performed with successive as follows ; coprecipitation→boiling→drying→heat treatment. The conventional process was characterized by the washing after the coprecipitation. The conditions determined as optimum for preparing the fine powders with best values of σs= 90.5 × 10-6 Wb⋅m/kg, HcJ=350.1kA/m, average anisotropy field HAavc=915.1 kA/m and Tc= 464°C are as follows: solution composition ; Fe3+/Sr2+=10.5 ; pH=13.0 ; heat treatment ; 1000°C for 2hs in air.
