Abstract

This stud deals with the conditions for the Formation of Ba-Ferrite by Hydrothemal synthesis Suspensions Containing either iron(III) hydroxide or hydroxide oxide and barium ians were subjected to autoclavings at various temperatures from 150 to 30$0^{\circ}C$. A ferromagnetic precipitate BaO.$6Fe_2O_3$ consisting of hexagonal plate-like particle was obtained by suitable combination of temperature and concentration of KOH
