摘要： A method for crystallizing substances, which are dissolved in a liquid at zero-gravity. In order to limit the extent of lattice defects occuring in the crystallized monocrystals as much as possible, it is provided, that the liquid during the crystallization is held as a quasi freely suspended liquid sphere and the substance in the liquid is crystallized using methods known per se. The liquid sphere is expediently held suspended within a space, which is limited from the outside by retaining elements. In a corresponding device, the retaining elements can be placed on the interior walls of a container.

摘要： In a system and method for producing ultrafine particles and ultrafine fibers of a given source material by evaporating and condensing the material in a gas atmosphere that includes inert gas. A smaller, more narrow size distribution is accomplished by producing the particles and fibers in a microgravity environment in order to reduce particle coalescence caused by convection currents. Particle coalescence also is reduced in an Earth gravity environment by controlling the convection currents. Condensed particles are collected either by providing an electrostatic field or a spatially varying magnetic field or by causing the gas to move through a filter which collects the particles. Nonferromagnetic material fibers are produced and collected by electrodes which produce an electro- static field. Ferromagnetic particles are collected by spatially varying magnetic fields.

The present invention relates to a technology for manufacturing a granular monocrystal, wherein: melt of melted raw material is made into a supercooled spherical melt; while the melt is levitated under microgravitational conditions, the free energy of a portion of the surface of the melt is reduced, and a monocrystal is grown. A monocrystal manufacturing device 31 comprises: a gold image furnace 35, a chamber 33, a raw material supply/retention mechanism 38; a drop tube 36 and a drop tube 37; a rotating plate 39; a recovery vat 40; and the like. Raw material 32a of semiconductor material is heated and melted and allowed to free fall in a vacuum inside drop tubes 36, 37. During the drop, rotating plate 39 comes into contact with a portion of the surface of supercooled spherical melt 32b, and a crystal nucleus is generated. From this crystal, a monocrystal is grown, and a spherical monocrystal 32c is formed, and this is recovered in recovery vat 40.

摘要： A detection or safety system is disclosed for preventing leakage of harmful gases when fragile ampoules break during heating of components in crystal growth experiments. In the preferred embodiment, the system includes an inner silica ampoule to house the components and reaction product; an outer silica ampoule that encases the inner ampoule, leaving a gap between them; an inert gas (preferably neon) that is normally trapped in the gap; and a metal canister that houses or contains the ampoules. If the pressure becomes too great within the inner ampoule, during heating by the crystal growth furnace, both ampoules may break. If that occurs, the neon is released, where upon its presence is sensed by a thermal conductivity detector ("TCD"). The TCD then sends off a signal to a controller which shuts off the furnace power. The resulting decrease in temperature releases the pressure and prevents the canister from being breached. This keeps potentially harmful gases contained within the canister, instead of escaping from the system.
