Combustion synthesis and structural characterization of theTiB2?(Na2O.2B2O3?Al2O3) composites
Original language description
Two TiB2:(Na2B4O7?Al2O3)=3:5 and TiB2:(1.28Na2B4O7?Al2O3)=6:7 compositions, named 5DB and 7DB respectively, were prepared by combustion synthesis in simultaneous mode at 800, 900 and 1000 °C. X-ray diffraction, differential scanning calorimetry (DSC), UV?vis and room and high temperature Raman measurements were carried out to investigate the combustion products. The crystalline phase of the 5DB composite yielded at 1000 °C (5DB_1000), which represents 62 wt%, mostly consists of TiB2 (93 wt%) while Ti2O3accounts for only 7 wt%. Proportion of the tetrahedral boron atoms, N4, in the blank and embedding sodium aluminium borate matrices was found from the high frequency Raman spectra using a constrained-width model in order to agree with the literature NMRdata.
