Abstract
The influence of binder amount (up to 2.3 wt %) on combustion of Ti–C granules containing polyvinyl butyral (PVB) as a binder and gasifying agent (two in one) was explored. For the first time, we managed to observe a mode of convection-driven combustion of Ti–C granules in the absence of external gas flow and formulated necessary conditions for such an event.
