The volume resistivity of boron nitride samples was determined as a function of temperature in the range 100–600C. In plots of log resistivity vs. reciprocal temperature for boron nitride bodies prepared from the same lot of boron nitride, similar curves were obtained. These curves consisted of two straight-line regions — one above 400C and another below 300C. The level of the resistivity for each test specimen depended upon the temperature at which the sample was heated before measurement and also upon the care taken in excluding impurities from the specimen during its preparation. The slopes of the curves in the straight-line regions did not change with different fabrication conditions.
