Thermal Property Measurement of Yamato Meteorites
The thermal diffusivity and specific heat of five Yamato meteorites (Yamato-7301,-7308,-74191,-74371 and -74647) were measured. Thermal diffusivity measurement was conducted under vacuum ((10)^<-3> mmHg or below) over the temperature range 150 to 550K. The temperature variation of thermal diff...

| Summary: | The thermal diffusivity and specific heat of five Yamato meteorites (Yamato-7301,-7308,-74191,-74371 and -74647) were measured. Thermal diffusivity measurement was conducted under vacuum ((10)^<-3> mmHg or below) over the temperature range 150 to 550K. The temperature variation of thermal diffusivity is very small at the temperatures 300-500K. Yamato-7308 (howardite) exhibits a lower diffusivity than other samples (ordinary chondrites). The specific heat of the samples was measured in one atmosphere air over the temperature range 270 to 420K. The temperature variation of the specific heat is found to be almost identical for all samples. |
