An instrument has been developed to measure the thermal conductivity of dense ceramic materials over the temperature range 20° to 200°C. A cylindrical ceramic specimen 1/2 in. in m diameter by 1/2 in. long is used in the instrument. hessures lower than 1μ of mercury are used to reduce heat losses and to permit rapid attainment of steady‐state conditions.
