Hello everyone(adsbygoogle = window.adsbygoogle || []).push({});

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!
