This paper describes the possibility of effect on the thermokinetic characteristics of the combustion process (SH-synthesis) with the help of modifying additives of inorganic and organic compounds containing bound water and ammoniac group. SH-synthesis was carried out by means of the furnace method under the conditions of selfignition of the sample (SiO_2+37.5%Al) placed in the preheated furnace. The combustion thermograms have shown that the modifying quartz additives exert a significant effect on all combustion parameters including the induction period, combustion rate, maximum combustion temperature and the change of heat conditions at the after burning stage (postprocesses). The presence of a sufficient amount of bound water and ammonia group in the modifying additives positively effects the increase in the amount of the matrix phase (corundum) and aluminium nitride in synthesis products.
