    Abstract: 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.

  • Patent number: 6793883
    Abstract: A method and system for reducing stress corrosion cracking in a hot water system, such as a nuclear reactor, by reducing the electrochemical corrosion potential of components exposed to high temperature water within the structure. The method includes the steps of: providing a reducing species to the high temperature water; and providing a plurality of noble metal nanoparticles having a mean particle size of up to about 100 nm to the high temperature water during operation of the hot water system. The catalytic nanoparticles, which may contain at least one noble metal, form a colloidal suspension in the high temperature water and provide a catalytic surface on which a reducing species reacts with least one oxidizing species present in the high temperature water. The concentration of the oxidizing species is reduced by reaction with the reducing species on the catalytic surface, thereby reducing the electrochemical corrosion potential of the component.

  • Publication number: 20030158028
    Abstract: No-bridging fluorine sites in calcium fluoride (CaF2) caused by lanthanide, transition metal or actinide impurities are eliminated by doping the CaF2 with sodium or another monovalent anionic dopant during or after growth of the crystal. This doping technique may be applied in the growth of other UV-transmissive fluoride materials in a family designated by a general formula Z:XFN where X is one or some combination of magnesium, calcium, zinc, strontium, cadmium, and barium, Z is one or some combination of lithium, sodium, potassium, rubidium, cesium, thallium, copper, silver and gold, and N is an integer in the range 1 through 6, and dependant on X. Elimination of the non-bridging fluorine sites can provide solarization resistant materials with low UV absorption even when the material contains sufficient lanthanide transition metal, or actinide impurities to cause the fluoride materials to be highly absorbing for UV radiation in the absence of the monovalent anion doping.
