Sintering is a process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction.

It is used to create material with specific features that would not be effective if created with a different system.

It is a densification process that at the same time provides a significant decrease of the porosity in the interstices.

This technique, also applied to metals and polymers, allows the material to solidify at temperatures lower than its melting point.
