    摘要： PURPOSE:To obtain high purity uniform fine particles of a noble metal or foil having no stuck impurities with high production efficiency by capturing a noble metal evaporated by heating in a vacuum bell jar by a capturing body placed in the bell jar. CONSTITUTION:A bell jar 1 is evacuated and a noble metal 8 is evaporated by heating in the vacuum bell jar 1. The evaporated noble metal 8 is captured by the surface of a capturing body 11 placed in the bell jar 1 to form fine particles or foil. By this method, high purity uniform fine particles of a noble metal or foil having no stuck impurities is obtd. with high production efficiency.

    摘要： PURPOSE:To continuously perform multistage gaseous phase reactions in a series of systems, by constituting a reaction apparatus by arranging a plurality of reaction chambers having respectively different energy applying means along the flow passage on the downstream side of a nozzle injecting a raw material. CONSTITUTION:When the ratio of the pressure in a raw material chamber 7 and that in a reaction chamber 2a is set to a critical pressure ratio or less, the outlet flow velocity of a contracting and expanding nozzle 1 becomes supersonic velocity and raw material can be injected at supersonic velocity. When the raw material is injected in a definite direction as the proper expanded stream of supersonic velocity mentioned above, the raw material straightly advances while holds the jet stream cross-section immediately after injection to be formed into a beam stream. By this method, the raw material is injected in reaction chambers 2a, 2b and a collection chamber 6 while diffusion is suppressed to the min. in a spatially independent state generating no interference with the wall surfaces of said chambers.

    摘要： PURPOSE:To easily produce and recover ultrafine particles by sticking the ultrafine evaporating particles formed by heating and evaporating the raw material to be made into the ultrafine particles in a vacuum vessel to a cooling body such as ice then taking out the cooling body and thawing the same. CONSTITUTION:A refrigerant such as freon is circulated into a metallic substrate 7 through an inlet 8 and an outlet 9 in the vacuum vessel 1 to cool the substrate and to form a cooling body layer 10 of ice or dryice, etc. on the substrate surface. After the inside of the vacuum vessel 1 is evacuated through a discharge hole to a vacuum, a material 5 such as Ni for the ultrafine particles in a crucible 3 is heated to evaporate by a electron gun 4. The ultrafine particle-like Ni vapor 6 deposits successively on the cooling body layer 10 such as ice or dryice on the substrate 7 surface to form the ultrafine particle layer 11 of Ni. Such layer is taken out of the vacuum vessel 1 and the ice or dryice is thawn or sublimated by which the ultrafine particles of Ni are recovered.

    摘要： PURPOSE:To produce efficiently hyperfine particles of one of various materials by irradiating layer light on the material under conditions which generate bloom. CONSTITUTION:A material 3 such as a metal, alloy, nonmetal or compound is placed at the bottom of a chamber 2. Laser light 4 is emitted from a laser light source 8, passed through a condenser 7 and a glass plate 1 and irradiated on the material 3. At this time, bloom 9 is generated between the glass plate 1 and the material 3. By the energy of the laser light 4, the material 3 is turned into hyperfine particles and dispersed in the chamber 2. A carrier gas 5 is then introduced into the chamber 2 to collect the produced hyperfine particles in a collecting chamber 6.
