  • Publication number: 20150144832
    Abstract: A crystalline ferromagnetic material based upon nanoscale cobalt carbide particles and a method of manufacturing the material via a polyol reaction are disclosed. The crystalline ferromagnetic cobalt carbide nanoparticles are useful for high performance permanent magnet applications. The processes are extendable to other carbide phases. Fe- and FeCo-carbides are realizable by using as precursor salts Fe-, Co-, and mixtures of Fe- and Co-salts, such as acetates, nitrates, chlorides, bromides, citrates, and sulfates. The materials include mixtures and/or admixtures of cobalt carbides, as both Co2C and Co3C phases. Mixtures may be a collection of independent particles of Co2C and Co3C or a collection of particles which consist of an intimate combination of Co2C and Co3C phases within individual particles. The relative proportions of these two phases and the morphology of each phase contribute to their permanent magnet properties, particularly at room temperature to over 400 K.

    Abstract: A method and apparatus for growing truly bulk In2O3 single crystals from the melt, as well as melt-grown bulk In2O3 single crystals are disclosed. The growth method comprises a controlled decomposition of initially non-conducting In2O3 starting material (23) during heating-up of a noble metal crucible (4) containing the In2O3 starting material (23) and thus increasing electrical conductivity of the In2O3 starting material with rising temperature, which is sufficient to couple with an electromagnetic field of an induction coil (6) through the crucible wall (24) around melting point of In2O3. Such coupling leads to an electromagnetic levitation of at least a portion (23.1) of the liquid In2O3 starting material with a neck (26) formation acting as crystallization seed. During cooling down of the noble metal crucible (4) with the liquid In2O3 starting material at least one bulk In2O3 single crystal (28.1, 28.2) is formed.

  • Publication number: 20130200293
    Abstract: The invention discloses a La(Fe,Si)13-based hydride magnetic refrigeration material comprising multiple interstitial atoms and showing a high-temperature stability and a large magnetic entropy change and the method for preparing the same. By reintroducing interstitial hydrogen atoms into an interstitial master alloy La1-aRaFe13-bSibXc through a hydrogen absorption process, a compound with a chemical formula of La1-aRaFe13-bSibXcHd and a cubic NaZn13-type structure is prepared, wherein R is one or a combination of more than one rare-earth element, X is one or more C, B and the like or their combinations. A desired amount of hydrogen is obtained through a single hydrogen absorption process by means of controlling the hydrogen pressure, temperature and period in the process of hydrogen absorption. The compound can be stable under normal pressure, at a temperature of room temperature to 350° C., that is, the hydrogen atoms can still exist stably in the interstices.
