What is Sintering?

Sintering is the bonding of adjacent powder particle surfaces in a mass of metal powders, or a compact, by heating. Also, a shaped body composed of metal powders and produced by sintering with or without prior compaction.

Other common names and related subjects are: cold/hot isostatic pressing, liquid phase sintering, and metal injection molding.*
