Abstract
The combustion synthesis (SHS) of titanium silicide (Ti5Si3) was investigated. The main combustion reaction (thermal explosion) occurs in the presence of a liquid phase and is usually preceded by a relatively small reaction in the solid state. The influence of Ti particle size on the dominance of each of these types of reactions was investigated. SEM observations and X‐ray diffraction analyses indicate that the combustion synthesis of Ti5Si3 proceeds according to the following sequence: TiSi2→ TiSi → Ti5Si4→ Ti5Si3.Keywords
