Abstract—Shape and polarity of thermo-emf signals arising during combustion of Ti–хB mixtures (x = 0.75–5.5) in conditions of quasi-static compression were found to depend on boron content x: emf signal was positive for x ≤ 1, negative for 1.5 ≤ x ≤ 3.0, and short negative for x ≥ 3.5. Generation of positive emf signals was associated with the n-type conductivity of Ti while negative ones, with the p-type conductivity of boron.
