摘要： Upon producing a transparent polycrystalline material, a suspension liquid (or slurry 1) is prepared, the suspension liquid being made by dispersing a raw-material powder in a solution, the raw-material powder including optically anisotropic single-crystalline particles to which a rare-earth element is added. A formed body is obtained from the suspension liquid by means of carrying out slip casting in a space with a magnetic field applied. On this occasion, while doing a temperature control so that the single-crystalline particles demonstrate predetermined magnetic anisotropy, one of static magnetic fields and rotary magnetic fields is selected in compliance with a direction of an axis of easy magnetization in the single-crystalline particles, and is then applied to them. A transparent polycrystalline material is obtained by sintering the formed body, the transparent polycrystalline material having a polycrystalline structure whose crystal orientation is controlled. In this calcination step, after subjecting the formed body to primary sintering at a temperature of 1, 600-1, 900 K, the resulting primarily-sintered body undergoes hot-isotropic-press sintering (or HIP processing) at a temperature of 1,600-1,900 K.

摘要： A heater for crystal formation provided with at least a terminal portion supplied with an electric current and a heating unit using resistance heating. The heater surrounds a crucible containing a raw material melt, and is used for crystal formation by a Czochralski method. The heater characterized by having a uniform heating distribution for the raw material melt after deformed in use for crystal formation. Consequently, the invention solves the conventional problem that a deformed heating unit of a heater used in formation of crystal causes a nonuniform temperature distribution in the raw material melt, which hampers formation of monocrystal resulting in unstable quality of the crystal.

摘要： A system for growing silicon crystals that facilitates controlling a shape of a melt-solid interface is described. The crystal growing system includes a heated crucible including a semiconductor melt from which a monocrystalline ingot is grown according to a Czochralski process. The ingot is grown on a seed crystal pulled from the melt. The method includes applying an unbalanced cusped magnetic field to the melt, and rotating the ingot and the crucible in the same direction while the ingot is being pulled from the melt.

摘要： A method for producing a silicon single crystal comprising growing the single crystal(6) through pulling up the crystal from a silicon melt (3) in a quartz crucible (4) while applying a horizontal magnetic field (10), characterized in that crystal growth is carried out in a manner such that either of a higher temperature portion and a lower temperature portion which are formed on the surface of the silicon melt (3) in the quartz crucible (4) is positioned at a solid-liquid interface observed during the crystal growth or in a manner such that a magnetic field at a crystallization center on the surface of the silicon melt (3) in the quartz crucible (4) has a strength wherein the ratio of its perpendicular component(12) to its horizontal component (11) is 0.3 to 0.5. The method can be used for producing a silicon single crystal rod having a highly uniform concentration distribution for interstitial oxygen atoms in the direction of crystal growth with high productivity and in good yield in the horizontal magnetic field-applied CZ method.

摘要： The invention relates to the field of material technology and concerns a method and device for the fused metal production of conducting alloys, which find application, for example, as materials for high strength permanent magnets. The aim of the invention is disclosure of a method and device whereby the seed formation, proliferation and transformation properties of forming phases and thus the structure of the solidifying alloys can be influenced. Said aim is achieved, by means of a fused metal production of conducting alloys in which the flow within the melt is influenced by an electromagnetically-generated volume force, to give a non-flowing condition and further, by means of a device for the fused metal production of conducting alloys, whereby a secondary coil is arranged above or below the primary coil and both coils comprise a dedicated resonant circuit, by means of which a phase shift may be controlled.

摘要： An unmelted substance (6) is disposed in a high magnetic field with a gradient to keep the unmelted substance (6) in a floating condition by a magnetic force produced by a magnetic field gradient and the floating unmelted substance (6) is heated and melted by rays of light from a heating light source (7), or hot-wire irradiation or a resistance heater. Then, heating by rays of light or hot-wire irradiation or the heater is stopped and the molten substance kept in a floating condition is cooled. Since the unmelted substance (6) in a floating condition is melted and cooled by using a magnetic force in a dummy micro-gravitational field, a material having an ideal shape and surface can be obtained.
