Abstract
MgAl2O4/Ti(C,N) composites were synthesized through aluminothermic reaction between Al,TiO2,MgO
powders and phenolic resin in coke bed condition. Effect of addition of carbon black and sugar into the mixture at
different temperatures were investigated. The phases and microstructures of samples were investigated by X-ray
diffraction (XRD) and scanning electron microscopy (SEM). MgAl2O4/Ti(C,N) composites without additive were
obtained after heat treatment at 1600?C. With addition of carbon black TiC, TiN and Ti(C,N) were appeared after firing
at 1400?C and formation of spinel/Ti(C,N) composites were completed at 1600?C. In sample containing sugar,
MgAl2O4-Ti(C,N) composite were completely synthesized at 1400?C. In this sample crystallite size of Ti(C,N) were 32
nm and carbon content of titanium carbonitride (Ti(C,N)) reached to 0.442 value.
