Abstract
Due to uncertain availability of nickel at reasonable
prices in the world market for the manufacture of alnico
magnets for diverse uses in the light electrical industry,
there is an urgent need for their replacement hy the
barium ferrite magnets which can easily be made at low
cost from the indigenously occurring raw materials. The
ferrite magnets are made from principal ingredients
barium carbonate and iron oxide by conventional powder
metallurgy techniques employed for the fabrication of
metal and ceramic components. The paper describes in
some detail various steps involved in the manufacture of
these magnets and different items of machinery required
at each step. Importance of proper mixing, ball milling,
compacting and sintering to obtain optimum properties is
also discussed.
