| Abstract: | The laser-driven pyrolysis of BC13/H2 system was used to produce boronultra Fme powders with laser power of 300W.Reaction flame and models,and influence of technology parameters on reaction flame were monitored by non-contact measurement of temperature.Powder density in flame was monitored by a He-Ne laser and the dynamicprocess could be detected. Calculations concerned was described, and distribution of powders in the flame was measured. |
