    OverviewGeneral sinteringCeramic sinteringSintering of metallic powdersPlastics sinteringLiquid phase sinteringElectric current assisted sinteringPressureless sintering

    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 together and creating one solid piece. Because the sintering temperature does not
