[Problems to be Solved] A neutron scintillator excellent in neutron detection efficiency and n/γ discrimination ability, and a metal fluoride eutectic preferred for the neutron scintillator are provided.[Means to Solve the Problems] A metal fluoride eutectic having a cerium-containing calcium fluoride crystal phase and a lithium fluoride crystal phase present in a phase-separated state, and a neutron scintillator comprising the metal fluoride eutectic.
摘要:
The present invention relates to a method for the preparation of solar grade silicon comprising crystallization of large high purity silicon crystals in a hyper eutectic binary or ternary alloy containing silicon, or a refined silicon melt, wherein small silicon crystals are added to the melt and the resulting large silicon crystals are separated from the melt. The separation may be performed by centrifugation or filtration.

A PROCESS FOR FABRICATING METAL-METAL SALT ELECTRODES COMPRISING FORMING A COATING OF A BINARY METAL SALT COMPOSITION ON A METAL SUBSTRATE AND LEACHING A SOLUBLE COMPONENT FROM THE COMPOSITION. A POROUS METAL SALT COATING IS THEREBY FORMED ON THE METAL SUBSTRATE. PREFERABLY THE BINARY SALT COMPOSITION IS A EUTECTIC COMPOSISTION WHICH HAS A LOW METLING POINT AND PROVIDES A POROUS STRUCTURE AFTER LEACHING.
