    摘要： An ignition element for use in igniting a high-frequency plasma torch is ungrounded and displaceable. When a tip end of the ignition element is positioned in a location in a gas to be formed into a plasma, which flows under normal pressure, and a high-frequency energy is applied to the above location in the gas flow, the gas is ignited into a high-temperature plasma in a small period of time shorter than 1 second. After the gas has been ignited, the ignition element is immediately retracted out of the location. The ignition element may be in the form of an ignition rod of metal or an ignition tube of quartz or the like. Where the ignition rod is used, it instantaneously contacts the high-temperature plasma upon ignition so that the high-temperature plasma is of high purity consisting only of the component of the gas. The ignition tube may be used for producing a high-temperature plasma of higher purity on and after ignition. The ignition tube is employed while a pressure therein is reduced. A glow discharge is generated in the ignition tube of the reduced pressure by applying the high-frequency energy, and the gas flowing outside of the tube is ignited by the glow discharge into a plasma.

    摘要： In preparing superfine particle in a reaction chamber by evaporation-in-gas method or on such processes as PVD or CVD using arc- or high-frequency plasma wherein in the proximity of the inner surface of the said reaction chamber, a vessel provided with a number of pores thereon is arranged and gas consisting of given components is introduced into the space between the inner surface of the chamber and the vessel, and spouted through the said pores on the vessel. The resultant superfine particle produced in the chamber and being in Brownian movement or in thermal migration does not adhere to the surface of the vessel by being separated from the vessel by the spouting gas so that the gas containing superfine particle is directed securely to the collecting path, wherein the vessel is made of the material not reactive with the resultant superfines but resistant to heat.
