摘要

In this work there are presented the results of experimental researches which had the goal to establish the thermal effect of BaCO_3 and α- Fe_2O_3 homogeneity mixture heated in microwave, used to processing barium ferrite W type by pyrosynthesis.There was used thermal-gravimetric analysis with a derivatograph reordered for microwave heating of samples containing iron oxides with different grain size.Experimental results emphasized that the microwave heating comparatively with resistor heating, lead to a lower synthesis temperature of hexaferrite of about 150 ℃ , using oxides with grain size suitable to S_(BET)= (7-10) m~2/g.
