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.

Sintering - Wikipedia

Sintering or frittage is the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction. Sintering happens naturally in mineral deposits or as part of a manufacturing process used with metals, ceramics, plastics, and other materials. The atoms in the materials diffuse across the boundaries of the particles, fusing the particles together and creating one solid piece. Because the sintering temperature

The degree of agglomeration of a system is determined by two factors: the sintering rate of two contacting particles and the regulating ability of the movement of particles. When the sintering rate is high while the regulating ability is weak, agglomeration happens. This opinion is consistent with that suggested by Kadusnikov et al. [14,15].
