Title:
ALLOY CASTING APPARATUSES AND CHALCOGENIDE COMPOUND SYNTHESIS METHODS
Document Type and Number:
WIPO Patent Application WO/2008/060926
Kind Code:
A3
Abstract:
A chalcogenide compound synthesis method includes homogeneously mixing solid particles and, during the mixing, imparting kinetic energy to the particle mixture, heating the particle mixture, alloying the elements, and forming alloyed particles containing the compound. Another chalcogenide compound synthesis method includes, under an inert atmosphere, melting the particle mixture in a heating vessel, removing the melt from the heating vessel, placing the melt in a quenching vessel, and solidifying the melt. The solidified melt is reduced to alloyed particles containing the compound. An alloy casting apparatus includes an enclosure, a heating vessel, a flow controller, a collection pan and an actively cooled quench plate. The heating vessel has a bottom-pouring orifice and a pour actuator. The flow controller operates the pour actuator from outside the enclosure. The quench plate is positioned above a bottom of the collection pan and below the bottom-pouring orifice.
