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.
Ceramic sintering advantages.
The general properties of ceramic material present the following advantages.
High wear heat pressure and chemical attack resistance gas and liquids.
Cost economy compared with other processes.
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 allows to obtain complex shapes directly from the compacting tooling without any machining operation like teeth splines profiles frontal geometries etc.
Calcium hydroxyapatite is a material very similar to what makes up your bones.
Ceramic is a polymer coated silicon carbide sic powder that provides exceptional dimensional accuracy because only 20 by volume of the powder is sintered.
The part once created with an sls machine is then fired in a kiln and only the ceramic part survives.
Good mechanical characteristics.
Sintering is a ubiquitous processing step for manufacturing ceramics for a diverse set of applications.
