Abstract: PURPOSE:To obtain the titled ultra-fine particules catalyst by a completely dry process by using the vapor of a metal or its compd. formed by sputtering to deposit ultra-fine particles on a fibrous catalyst carrier. CONSTITUTION:A DC sputtering or RF sputtering process is used for the sputtering. The fibers in the form of cotton and cloth can be used as the catalyst carrier fibers. The inorg. fibers of gamma-alumina, etc., an org. polymer, and metallic fibers can be used as the fibers. The surface of the fiber can be modified with the ultra-fine particles of the substance to be used as the catalyst, and metals such as Au and their alloy or compd. can be used as the ultra-fine particulate catalyst. The kind of ultra-fine particles can be changed by changing the target material in the sputtering process. The ultra-fine particles are fused to each other by heat treatment.

Abstract: PURPOSE:To easily produce ultrafine oxide particles with extremely high efficiency with an extremely simple device by burning metallic powder in oxygen (contg. gas). CONSTITUTION:A carrier gas ejected from a nozzle 11 forces the metallic gas in a powder storage vessel 1 to solar up and conveys the powder by the gaseous flow through a transport pipe 2. The gas is then ejected from a combustion nozzle 3 into a combustion pipe 4. The oxygen can be further replenished thereto through an oxygen nozzle 61 provided to the periphery of the nozzle 3. The smoke-like ultrafine oxide particles are formed when the metallic powder ejected into the combustion pipe 4 is ignited and burned by a pilot burner 41 attached to the pipe 4. The formed ultrafine oxide particles are collected by the collector 5. The quality of the ultrafine oxide particles obtd. by such extremely simple device is approximately equal to the quality of the particles obtd. by the conventional dry process. The production of the ultrafine oxide particles with the extremely high efficiency is thus made possible without using costly raw material, device and fuel.

CONSTITUTION:An object 1 which is to be treated and consists of the superfine powder or fine fibrous material of metals, alloys, semimetals, intermetallic compds., inorg. compds., or heat resistant org. polymers, etc., is put into a heat resistant crucible 2 made of alumina, etc., and the crucible is put into a heat resistant vessel 4 having a heater 3. The vessel 4 is further put into an external vessel 5 and the inside thereof is evacuated to a high vacuum by a discharge system 6; thereafter, hydrocarbon, CO, H2S, O2, NH3. and other gases are supplied as the reactive gases together with an inert gas, such as Ar, from a gas supply system 8 are supplied therein. The superfine powdery or fine fibrous material 1 to be treated in the crucible 3 is simultaneously heated to, for example, 400 to 1000 deg.C by the heater 3 and the ultra-thin film of the reaction product by the cracking of the reactive gases is formed on the surface thereof.

Abstract: PURPOSE:To produce hyperfine particles having reformed surface coatings by evaporating an evaporating material such as metal or metalloid in the presence of a reactive gas such as a gaseous mixture composed of a gaseous hydrocarbon or carbon monoxide and inert gas. CONSTITUTION:A raw material 2 is placed on a supporting base 1 of the evaporating raw material and the inside of a hermetic vessel 3 is evacuated by an evacuation system 4. A reactive gas and inert gas is introduced into the vessel by a gas supply system 5. The raw material 2 serves also as an electrode for an arc discharge and makes a pair with an electrode 6 consisting of a bar- shaped carbon. The arc discharge 7 is generated by such electrode. The raw material supporting base 1 and the electrode supporting base 8 are cooled by water cooling means 9, 10. The evaporating raw material forms the hyperfine particles in the gas and forms the films. The hyperfine particles are sucked together with the gas by a suction pump 11 and are captured by a capturing device 12. The gas is returned to the inside of the hermetic vessel by a circulating means 13.

Abstract: PURPOSE:To form a uniform thin film having desired properties by a vapor phase method and to reform the surface of powder or fibrous material by heating the powder or fibrous material in an atmosphere of a reactive gas or gaseous mixture composed of the reactive gas and inert gas. CONSTITUTION:The powder or fibrous material 1 is put into a crucible 2 and the crucible is put into a heating furnace where a carbon heating element 3 or the like is used as a heat source. The heating furnace is installed to a heat insulating vessel 4 and the inside of an outside vessel 5 is evacuated. The reactive gas or the gaseous mixture composed of the reactive gas and inert gas is introduced from a gas supply line 8 into the vessel upon confirmation that a prescribed pressure is attained therein. The material is heated by the energization from conducting terminals 9. The thin film is formed on the surface of the powder or fibrous material by such treatment. This treatment is applicable to the case of forming a graphite film, etc., on the surface of nickel powder or silicon powder.

Abstract: PURPOSE:To produce ultra-fine oxide particles having extremely high crystallinity, easily and economically in high yield, by mixing molten and atomized metal with oxygen(-containing gas) to effect the combustion of the metal. CONSTITUTION:Metal (e.g. aluminum) is thrown into a smelting tank 11 through an inlet port, melted by heating with the heater 12, transferred through the pipe 3 by the pressure of gas supplied from the gas bomb 15 and sprayed and atomized at a high speed from the orifice 21 of the molten metal spray nozzle 2. In the above apparatus, air and/or oxygen are sucked through the air-suction port 24 provided between the nozzle cover 23 and the cap 22, mixed with the atomized metal, and ignited with the igniter 25 placed in front of the nozzle 2. The metal is burnt in the combustion pipe 4 to form ultra-fine oxide particle fume. The ultra-fine particles are introduced together with the combustion exhaust into the ultra-fine particle collector 5 and collected.

Abstract: PROBLEM TO BE SOLVED: To economically and efficiently obtain homogeneous single-layer carbon nanotubes through a simple method by irradiating the carbon target containing a small amount of metal with a high-power carbon dioxide gas laser to effect the carbon gas laser evaporation in an inert gas atmosphere. SOLUTION: In this production, the carbon target substance and the atmospheric inert gas do not need to be heated. As an inert gas, are cited Ar, He or a variety of other gases, The carbon target substance may contain a small amount of metal as a catalyst, for example, graphite containing Fe, Co, Ni, Pt, Pd, Rh or the like, and is placed in a vessel. The gas pressure in the vessel caused by introduction of the inert gas is preferably set to, for example, 104-105 Pa. The high-pressure CO2 gas laser beam is desirably a continuous wave laser with an output power of 800-1,500 Watts. The laser beam can be irradiated almost at the rectangle to the target surface or at an angle less than 90 degree.
