Sources for resistivity of W depending on temperature

Click For Summary
SUMMARY

The discussion centers on the temperature-resistivity relationship of Tungsten (W) within the temperature range of 300 to 2500 K. The original poster, Zoroaster, seeks reliable data beyond the CRC Handbook, which contains inconsistent tables across different editions. A suggested resource is provided, linking to a publication from the American Physical Society that may offer more accurate data for this specific application.

PREREQUISITES
  • Understanding of resistivity and its dependence on temperature.
  • Familiarity with Tungsten properties and applications.
  • Basic knowledge of experimental physics and data analysis.
  • Access to scientific publications and databases.
NEXT STEPS
  • Research the publication linked from the American Physical Society for detailed resistivity data.
  • Explore additional resources such as the NIST database for material properties.
  • Investigate mathematical models for temperature-dependent resistivity beyond linear approximations.
  • Review experimental techniques for measuring resistivity in high-temperature environments.
USEFUL FOR

Researchers, experimental physicists, and engineers working with Tungsten in high-temperature applications, as well as anyone involved in materials science and electrical conductivity studies.

Hello everyone

I am trying to do an experiment involving a W bulb, in which I am completely dependent of knowing the temperature-resistivity relation of Tungsten in the temperature range 300 - 2500 K. The CRC handbook has some tables, but they have few data points and correlate poorly with each other (in different editions). Does anyone here know where else I can find a good table (or formula, although a linear relation is not precise enough)?

Any help would be much appreciated!
