Abstract:V članku poročamo o rezultatih raziskovalnega dela v okviru sodelovanja med Institutom "Jožef Stefan" in tovarno ISKRA Feriti, d.o.o., v katerem smo razvili nov postopek za masovno pripravo MnZn-feritov, ki temelji na pripravi feritnih prahov s hidrotermalno obdelavo izhodnih oksidov. Z omenjeno metodo smo dobili feritne prahove, ki so po fazni sestavo podobni tistim, pripravljenim po klasičnem keramičnem postopku. Priprava prahov po hidrotermalni metodi je zahtevala prilagoditev celotnega tehnološkega procesa priprave feritov. Prednost hidrotermalne metode pred klasičnim keramičnim postopkom je predvsem v manjši porabi energije, saj poteka termična obdelava oksidne mešanice pri relativno nizkih temperaturah (260 [kompozitum]C - 320 [kompozitum]C) ter bistveno krajših časih, hkrati pa se je izkazalo, da imajo hidrotermalni prahovi velik potencial pri pripravi feritov MnZn z izboljšanimi lastnostmi.

Title:The preparation of MnZn ferrites using a hydrothermal treatment of starting oxides
Abstract:This article reports the results of a project to develop a new method for the preparation of MnZn ferrites, which was performed in the framework of a cooperation between the Jožef Stefan Institute and ISKRA Feriti d.o.o. The new method, which is based on the hydrothermal preparation of ferrite powders with a hydrothermal treatment of the usual starting oxides, results in powders with a similar phase composition to that of calcined powder. The hydrothermal preparation of the ferrite powders demanded an adaptation of the whole technological process of ferrite production. The advantage of the hydrothermal method, when compared to classic ceramic technology, is mainly in the reduced energy consumption related to the low processing temperatures (260-320 [compositum]C) and times. The hydrothermally synthesized powders have great potential when it comes to the preparation of MnZn ferrites with improved magnetic properties.
Keywords:powder preparation, hydrothermal synthesis, magnetic materials, MnZn ferrites
