The influence of combustion temperature on the phase and morphological compositions of Si3N4‒Yb2O3 composites obtained by the SHS method

Year: 2024

Type: article

Abstract: The effect of combustion temperature on the phase composition and morphology of particles of SHS composites of the composition Si3N4‒Yb2O3 was studied. The combustion temperature was controlled using the silicon content in the reaction mixture. It was found that with an increase in the synthesis temperature, the content of α-Si3N4 decreases. Silicon ytterbium oxynitride is formed as a secondary phase. The morphology of the particles of the composition changes with an increase in the combustion temperature from the equiaxed form of α-Si3N4 to columnar crystals of β-Si3N4. Ill. 3. Ref. 7.
