Синтез наночастиц карбида кремния методом лазерного пиролиза смеси моносилана и ацетилена

The conditions of the laser-enhanced synthesis reaction of silicon carbide nanoparticles are determined and the nanoparticles are characterized. The gas-phase reaction of laser synthesis of SiC particles is observed at SiH4/C2H2 flow ratio in the range of 1.6-3.2. The temperature in the reaction zone was ~1400--1500ºC. Silicon carbide nanoparticles ~6 nm in diameter are produced and their composition is studied.

Co2 Laser Radiation

The conditions for the synthesis of silicon carbide nanoparticles in a SiH4/C2H2/Ar/He gas mixture under the action of CO2 laser radiation with a wavelength of 10.6 μm are determined. It was found that laser synthesis of SiC particles is observed when the ratio of gas flows SiH4/C2H2 is in the range of 1.6-3.2. The temperature in the region of the reaction zone was ~1400-1500°C. Silicon carbide nanoparticles ~6 nm in diameter were obtained and their composition was investigated.
