  • 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.
