Journal of research of the National Institute of Standards and Technology, 1998•ncbi.nlm.nih.govThe 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− 1 down to 8 W· m− 1· K− 1 and has an inverse-
temperature functionality. The results agree well with literature values for this material.

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