摘要： In the porous substrate loaded with porous nano-particles structure and one-step micro-plasma production method thereof, since the micro-plasma system enhances the electron density and promotes reaction speed in the reaction without generating thermal effect, the method may be performed at an atmosphere environment. The nano-particles also can be quickly obtained by aforementioned micro-plasma system. The electromagnetic field generated by the micro-plasma can drive the nano-particles to be loaded onto the porous substrate in a one step, rapid and low cost process to improve the conventional techniques which require a relatively long procedure time and a complicated process.

摘要： Methodologies, systems, and devices are provided for producing metal spheroidal powder products. Dehydrogenated and spheroidized particles are prepared using a process including introducing a metal hydride feed material into a plasma torch. The metal hydride feed material is melted within a plasma in order to dehydrogenate and spheroidize the materials, forming dehydrogenated and spheroidized particles. The dehydrogenated and spheroidized particles are then exposed to an inert gas and cooled in order to solidify the particles into dehydrogenated and spheroidized particles. The particles are cooled within a chamber having an inert gas.

摘要： Provided are a method and apparatus capable of producing fine particles with favorable particle size distribution. In a production method in which feedstock for fine particle production is supplied intermittently into a modulated induction thermal plasma flame, the feedstock is vaporized to form a gas phase mixture, and the mixture is cooled to produce the fine particles: a modulated induction thermal plasma flame in which the temperature state is time-modulated is generated; the modulated induction thermal plasma flame is switched between a high temperature state and a low temperature state; and when the modulated induction thermal plasma flame is in the high temperature state, the feedstock is supplied together with a carrier gas, and when the modulated induction thermal plasma flame is in the low temperature state, supply of the feedstock is suspended and a gas of the same type as the carrier gas is supplied.
