What Happens To A Ceramic Material When It Is Sintered

The sintering process in metallurgy.

What happens to a ceramic material when it is sintered.

The majority of metals can be sintered. Sintering is the process of fusing particles together into one solid mass by using a combination of pressure and heat without melting the materials. Dmitri kopeliovich sintering firing of ceramic materials is the method involving consolidation of ceramic powder particles by heating the green compact part to a high temperature below the melting point when the material of the separate particles difuse to the neghbouring powder particles. Sintering is generally used in the manufacture of ceramic products however the process can be used to fashion metal glass and plastic objects as well as composites and alloys.

Sintering is a heat treatment process in which a large quantity of loose aggregate material is subjected to a sufficiently high temperature and pressure to cause the loose material to become a compact solid piece. Common particles that are sintered together include metal ceramic plastic and other various materials. 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. As long as the raw material for a particular product is in a powdered form the product can be sintered.

The amount of heat and pressure administered during the sintering process is slightly less than the material s melting point. The ceramic studied is alumina chemical formula al 2 o 3 with and without dopants. 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. The driving force of sintering process is reduction of surface energy of the particles.
