Sintering | Article about sintering by The Free Dictionary

or agglomeration, in metallurgy, the heat process for pelletizing fines (ores, ore concentrates containing waste metals, and others), as components of the metallurgical charge, by sintering these materials in order to impart the necessary shape and properties (chemical composition, structure) to them for melting. Sintering takes place either by direct adhesion of separate heated particles of the charge as …

What is Agglomeration? - Glossary of Powder Mixing Technology ...

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.

Agglomeration - an overview | ScienceDirect Topics

Agglomerates form by various mechanisms, for example due to electrostatic forces between very small (nanoscale) particles, the formation of bridges between particles upon spraying of an additional liquid which may form solid bridges after evaporation of the liquid from a sprayed solution or suspension, or by thermal effects, for example sintering or glass transition, e.g. Ennis et al. (1991); Iveson et al. (2001); …
