| Abstract: | Combustion of silicon powders containing organic dopants in nitrogen gas under pressure was found to yield a mixture of α-Si3N4, β-Si3N4, SiC, and Si2N2O. Relative amount of these compounds in combustion product was found to depend on the pressure of nitrogen gas, type and
concentration of dopants, combustion geometry, and cooling rate. The formation of α-Si3N4 was found to occur in the presence of oxygen-containing dopants. The type of dopant was also found to affect the morphology
of product particles.
