Abstract
This report shows that magnetically isotropic and anisotropic compacts of BaFe12O19 or SrFe12O19 sinter to high density with controlled microstructure in the presence of a liquid phase. The liquid‐phase compositions are in the systems MO–SiO2 and MO–Al2O3–SiO2, M=Ba, Sr. Further, it is shown that systems containing MB2O4 as an additional component will give similar results at significantly lower temperatures. The resultant magnetic properties meet or exceed the appropriate magnet industry criteria for hard ferrite magnets.This publication has 4 references indexed in Scilit:
