title: Thermal Conductivity of Magnesium Oxide From Absolute, Steady-State Measurements.
abstract: The thermal conductivity of polycrystalline magnesium oxide has been measured over the temperature range from 400 K to 1300 K using a modified guarded-hot-plate design. Three different thicknesses of specimens having 93 % of theoretical density were tested to verify the operation, accuracy, and reproducibility of our apparatus. The measured thermal conductivity ranges from 30 W · m-1· K-1down to 8 W · m-1· K-1and has an inverse-temperature functionality. The results agree well with literature values for this material.
