The results showed that mechanical activation have an important role to promote exothermic reaction and Al2O3-B4C composite synthesis via combustion method. The mechanical activation decrease reaction temperature to lower than 700°C and increase reaction intensity without any effect on combustion reaction mechanism, so that, the sample synthesis was completely carried out in microwave at 12 second and 20 hours pre-mechanical activation. The results also support the possibility of boric acid using as raw material to combustion synthesis Al2O3-B4C composites. %> http://ijcse.ir/article-1-382-en.pdf %P 11-24 %& 11 %! %9 Research %L A-10-294-2 %+ %G eng %@ 2322-2352 %[ 2016
