A self-sustaining reaction for titanium aluminides production via alumino-calciothermic reduction of TiO?

摘要

Titanium aluminides can be produced via an alumino-calciothermic reduction of TiO? in presence of KClO?. This reaction, named KRH process, has been studied in this paper. The results show that after heating of starting materials with rate of 20°C/min, a self-sustaining reaction is ignited at about 550°C which led to the rapid increasing of system temperature to 1950°C during a short time of 192 s with a mean internal heating rate of around 437°C/min.
