What is Agglomeration? Glossary of Powder Mixing
Sintering. Sintering, also known as frittage, is a thermal agglomeration process during which the atoms within the materials diffuse and form bridges across distinct particles, joining them together. Sintering involves heating products without melting them, and as such is particularly well-suited for materials with very high melting points.

This happens at a certain elevated temperature, which is different for various materials. While still in solid state, diffused matter forms bridge-like structures between the surfaces, which solidify upon cooling.

Iron Ore Agglomeration Processes and their Historical
2015-12-28 The origin of sintering process goes back to 1887 when F. Haberlein and T. Huntington of England invented the process of agglomeration for sintering of sulphide ores.
