Thermal properties of materials

The electrical conductivity of high purity (99.8 pct) has been determined using both a‐c and d‐c techniques. Measurements were made at temperatures between 700° and 1000°C and in a nitrogen pressure range of 1–10−5atm. The electrical conductivity is independent of nitrogen pressure. Galvanic cell results indicate that ionic conduction is negligible. Over the experimental temperature range, the electrical conductivity of follows the equation
