Paper Title:
Researches Regarding the Barium W Ferrite Pyrosynthesis by Microwave Heating
  Abstract

In this work there are presented the results of experimental researches which had the goal to establish the thermal effect of BaCO3 and α- Fe2O3 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 0 C , using oxides with grain size suitable to SBET= (7-10) m2/g.
