  • HEAT TREATMENT DEVICE FOR MATERIAL IN POWDER FORM AND CORRESPONDING HEAT TREATMENT METHOD
    Publication number: 20150263332
    Abstract: A heat treatment device for a material in powder form, including a heat treatment furnace including a heating zone and a quenching tank. The quenching tank includes a container at least partially filled with a plurality of precooled solid elements, and the heat treatment furnace is mounted in a mobile manner to allow the content of the heat treatment furnace to be transferred to the quenching tank. A corresponding heat treatment method, for example, can implement manufacture of lamellar lithium manganese nickel magnesium oxide.
