Higher temperature of sintering, hot pressing, hot isostatic pressing, additives that decreases the friction of powders during sintering (MnS for example or some organic lubricants)

Thanks. Could you please let me know the lubricant that would help for better results

powder metallurgy text books may give you ideas, additives will depend on the metal you are trying to sinter. Some metals can be cold pressed to high density which will also help in sintering.

thanks. most of our bonds are iron based. normally we work with Fe, Cu, Sn, Zn, Ni, Co, Mn, Mo as Fe as major elements. we follow mechanically alloying and the diffusion it certain temp. is there any binder which could help to get cold compaction and better sinter density?
