Paint high T, high emissivity for Black Body simulation

Click For Summary
SUMMARY

This discussion focuses on identifying paints with high absorptivity and emissivity that can withstand temperatures exceeding 1000°C for use in vacuum environments. Participants suggest considering chemical treatments like gun bluing or parkerizing for achieving black coatings. Additionally, the importance of understanding the specific wavelength range for thermal infrared applications is emphasized, along with the potential use of quarter wavelength coatings to enhance transmission properties.

Hi all!
I would be interested in paints that show very high absorptivity/emissivity and that can withstand high temperatures (ideally above 1000°C) and used in vacuum. Do you have any commercial suggestions?

Thank you!

The energy flow through the paint will be in series with flow through the material that is being painted. What material will you be painting?
Chemical treatment of metal surfaces can give black coatings. Consider gun bluing or parkerizing.
Do you know the wavelength range required? Thermal IR only? Can you use quarter wavelength coatings to improve transmission?
