  text: The technical importance of paraffins as phase change materials (PCM) in heat
    storage systems increases. Knowledge on the thermal conductivity of paraffins
    is necessary for the design and optimization of heat storage systems. However,
    for most paraffins solely the thermal conductivity of the liquid state has been
    sufficiently investigated. For the solid state, precise thermal conductivity data
    are only known for a few paraffins, while only generalized values are available
    for the remainder, some of which contradict each other. In this study, a measurement
    setup based on the modified guarded hot plate method is developed. It is used
    to investigate the thermal conductivity of several paraffines in the solid state,
    including pure n-docosane and its compounds with different types and concentrations
    of graphite. For n-docosane in the solid state, the thermal conductivity is determined
    to be 0.49 W/(m K). A particle size of 200 μm with a spherical shape turns out
    to be optimal to increase the thermal conductivity. This allows the thermal conductivity
    of a compound with 10% graphite to increase by a factor of three compared to the
    pure paraffin. Furthermore, significant differences to thermal conductivity data
    from the literature are found.
