What happens to a ceramic material when it is sintered.

The driving force of sintering process is reduction of surface energy of the particles. Operation mode the liquid used for immersion must be stable and controlled. 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. 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.

The majority of metals can be sintered. The amount of heat and pressure administered during the sintering process is slightly less than the material s melting point. 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. 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.

The sintering process in metallurgy. We will measure a series of three sintered pellets natural sintering in air at three different temperatures will be used. Common particles that are sintered together include metal ceramic plastic and other various materials. The ceramic studied is alumina chemical formula al 2 o 3 with and without dopants.
