Here's a general range:
* At room temperature (20°C):
* 5.34 x 10^-8 Ω·m (This is a common value found in reference materials)
* At 0°C:
* 4.8 x 10^-8 Ω·m (This is a slightly lower value due to the effect of temperature on resistivity)
Important Considerations:
* Temperature: Resistivity increases with increasing temperature. The exact relationship is not linear, so you'll need to consult specific tables or equations if you need a precise value at a specific temperature.
* Purity: Impurities in the molybdenum will affect its resistivity. Higher purity molybdenum will generally have a lower resistivity.
* Annealing: The mechanical processing of molybdenum (e.g., cold working) can affect its resistivity. Annealing (heating and cooling) can help to reduce resistivity back to a lower level.
Where to find more specific data:
* Material Data Sheets (MDS): These sheets are provided by manufacturers of molybdenum and will contain detailed information about the specific properties of their products.
* Engineering Handbooks: Handbooks like the CRC Handbook of Chemistry and Physics often have tables of material properties, including resistivity.
* Online Databases: Databases like NIST Chemistry WebBook or ASM International can provide detailed information on the resistivity of molybdenum and other materials.
Remember to specify the conditions (temperature, purity, etc.) for which you need the resistivity value.
