    摘要： The invention relates to a latent heat storage material comprising a first phase change material, at least one second phase change material different from the first phase change material, and an expanded graphite material wherein the first phase change material and the at least one second phase change material are intermixed and the latent heat storage material exhibits a phase transition over a range of temperatures. The invention also relates to a process for the preparation of a latent heat storage material comprising combining a mixture of an expanded graphite material and a first phase change material with at least one different second phase change material.

    摘要： A process for the preparation of latent heat storage composites is provided. The process comprises the steps of preparation of an expanded graphite material with a bulk density between 5 and 200 grams/liter which is readily wetted by a liquid phase change material, preparation of a pre-compressed matrix or a packed bed of the expanded graphite material, and manufacture of a latent heat storage composite by infiltration of the matrix or a packed bed with a phase change material in a liquid state.

    摘要： Anode assembly for aluminium electrolysis cells comprising carbon anodes (2) with stubholes (5) and an anode hanger having stubs (4), whereas the anodes (2) are fixed to the anode hanger by cast iron (6), characterized in that the stubholes (5) are fully or partially lined with an expanded graphite lining (7).
    Such anode assemblies provide reduced voltage drop across the interface between the cast iron (6) and the carbon anode (7) and thus increase cell productivity significantly. Further, mechanical stresses in the stubhole (5) area are reduced. By further forming a collar (8) from the lining (7), the spilling of cast iron over the anode (2) surface is prevented and optionally a protective shot plug or a protective collar prevent direct contact of the hot electrolyte bath with the stub (4) and the cast iron (6).
