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 и m -1 и K -1 down to 8 W и m -1 и K -1 and has an inverse-temperature functionality.The results agree well with literature values for this material.
