    Composites in the TiB2-Na2O.B2O3.Al2O3 systems, TiB2-MBA (MB stands for sodium metaborate and A is Al2O3), were prepared by self-propagating high-temperature synthesis (SHS), in simultaneous mode. Selection of these compositions was ruled by the interesting properties of both TiB2 and double borates of alkali metal and aluminum. The structure of the obtained materials was evaluated by micro-Raman spectroscopy, from room temperature up to 6000 C, and X-ray Photoelectron Spectroscopy (XPS). Formation of the TiB2 and TiO2-xBx phases along with TiO2 as rutile were identified as titanium speciation in the grain phase embedded in a sodium aluminum borate matrix.
