Abstract

Ferritas de bario, (BaFe12O19) son ampliamente usadas como magnetos permanentes, principalmente debido a sus adecuada combinación de bajo costo y buenas propiedades magnéticas; sin embrago, muchos métodos químicos han sido investigados. Dentro de estos métodos, coprecipitación, Pechini y Combustión son los que mejores resultados han arrojado, principalmente porque son simples cuando se comparan con otros. En este trabajo fue preparada BaFe12O19, por estos tres métodos, cambiando algunos parámetros de interés y la temperatura de calcinación. Los difractogramas de rayos X de las muestras calcinadas muestran la formación de BaFe12O19 a temperaturas tan bajas como 800º C.
