Ceramic Sintering Process

The sintering or firing process provides the energy to encourage the individual powder particles to bond or sinter together to remove the porosity present from the compaction stages.

Ceramic sintering process.

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. During the sintering process the green compact shrinks by around 40 vol. At the end of the sintering process the synthetic graphite powder was still in the powder form and was easy to remove from the sintered body. Get ceramic pieces appropriate for the selected application.

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 driving force of sintering process is reduction of surface energy of the particles. The sintering process in the ceramic composite is considered to be a solid state sintering process 18. During this stage the microstructure of the samples evolves see figure 1.

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. While commonly related to powder processing of ceramic parts its important roles in other processes such as additive manufacturing nanotechnology and thin films are less commonly discussed. Several authors extensively studied the sintering of zta composites. Usually this is done by a sintering process which is a consolidation and densification step of the granular compact through the action of heat.

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. Indeed the zta composites offer advantages over the monolithic alumina during sintering. Full densification is achieved by sintering at temperatures up to 1800 c. As long as the raw material for a particular product is in a powdered form the product can be sintered.
