Sinter, sintering - Digitalfire

The sintering process begins in a clay when it has been fired high enough so that it no longer will slake or break down when exposed to water. Bisque fired ware has advanced to a higher state of sintering. Refractories can often be sintered to considerable strength because the high temperatures maximize particle packing and surface interaction.

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 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 ...
