Hi all - looking for help as a metallurgist - not a chemist.
For a powder metallurgy project I need a simple, solid, powdery nitrogen compound I can mix with metallic, compacted powder and heat to 500 deg C. I need it to liberate nitrogen to react with the metal surfaces. I was looking at copper cyanide but will this liberate toxic fumes on breakdown? Was also looking at such things as urea but want hydrogen-free if I can get it or the hydrogen might dissolve in my aluminium powder.
Any suggestions based on C-N materials?
Many thanks for any response.
