The using of rate-controlled sintering technology for improvement of strontium ferrite

The principles of the use of rate-controlled sintering technology for manufacturing permanent magnets of electric machines from strontium ferrite were considered. The technology of magnet production based on strontium ferrite used in production requires perfection aimed at improvement of electrical properties at the expense of ferrite density and structure. This paper shows the use of nonisothermal sintering conditions for achieving high density and fine-grain structure of strontium ferrite that provides a high level of its magnetic characteristics
