Sintering Iron Size

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 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.

The Sintering Process In Powder Metallurgy Ge

Sintering is a heat treatment commonly used to increase the strength and structural integrity of a given material.Powder metallurgy processes use sintering to convert metal powders and other unique materials into end-use parts.Sintering typically takes place in a single, elongated furnace with different temperature zones.
