The paper presents a study on the obtaining of NiAl and Ni3Al refractory intermetallics in their stoichiometric and homogeneity range, obtained by self-propagation high temperature synthesis, the thermo-explosion variant. The processing variables were the compacting pressure and the material chemical composition. The influence of unreacted materials green porosity on the sintered materials contraction/expansion was determined. The interdependence of the liquid amount appeared during synthesis of the reaction products and the green as well as final material porosity were established.
