Abstract: 

KRH process is a new way for producing titanium aluminide intermetallic compound on the basis of a complex reaction between tio2,  Al, Ca and kclo4 reacting materials. In this study ,the occurred phenomena in different temperature regions were investigated and a temperature region which the reaction had a self-propagating behavior was determined by temperature measurement in the reaction vessel and DTA analysis. It was found that the process was ignited via the reaction between kclo4 and Ca. A self propagating reaction started after the ignition of process.
