The powders calcined at 300°C/4h were analyzed by TG/DTA to study the temperature of organic matter decomposition. A systematic study of calcination temperature and time to the formation of the BBN phase was performed and the phase formation was accompanied by XRD. The calcined powders at 800°C during 2h were analyzed by infrared spectroscopy and by BET. The powders were isostaticaly pressed and sintered at temperatures ranging from 900°C to 1000°C. The ceramics were characterized by XRD to control the crystalline phase and by SEM to analyze the microstructure.149-154engBarium compoundsCalcinationCrystal microstructureCrystalline materialsDifferential thermal analysisInfrared spectroscopyPowdersScanning electron microscopySinteringSynthesis (chemical)Thermogravimetric analysisX ray diffraction analysisCrystalline phasePechini methodCeramic materialsArtigo10.4028/www.scientific.net/KEM.189-191.149WOS:000168303300025Acesso restrito2-s2.0-00351511759128353103083394
