  • Process for preparing strontium ferrites
    Patent number: 4062922
    Abstract: Oriented strontium ferrites which yield superior ceramic permanent magnets are produced by the four-step process ofA. preparing small particles of agglomerated less than 0.1 micron grains of ferric oxide and strontium oxide,B. maintaining the particles of agglomerated oxides at temperatures of from about 800.degree. C to 1100.degree. C for up to about 24 hours to cause the oxides to react (ferritize) and form less than 0.5 micron diameter crystallites of strontium ferrite,C. sintering the crystallites into a solid body either by maintaining them at from 1100.degree. C to 1300.degree. C for not more than two hours, or preferably by maintaining them at from 800.degree. C to 1300.degree. C while applying pressure, andD. hot forging the body by applying pressures of up to about 30,000 psi at temperatures of from 800.degree. C to 1300.degree. C.
