Reactive flash sintering of SrFe12O19 ceramic permanent magnets

Journal of Alloys and Compounds, 2022
Reactive flash-sintering technique has been used in order to obtain strontium ferrite magnets from a mixture of SrCO and FeO commercial powders. This technique allows preparing sintered SrFeO at a furnace temperature of just 973 K during just 2 min by applying a modest field of 40 V cm, instead of the conventional sintering process employed in ferrite ...
