This term describes a method of producing materials, as a result of which fine-grained, ceramic or even metallic materials are usually heated under pressure increase by temperatures below their own melting temperature.
This process is used above all in the ceramic industry, but also in metallurgy, whereby grainy or powdery materials are mixed and are bonded together by heat treatment. After the power mass has been placed in the mold of the required workpiece, either by pressing the powder mass or by forming and drying, as is used in the manufacture of clayware, the so-called green compact is compacted and age-hardened by heat treatment below the melting temperature.
Sintering enables the melting of base materials, which would otherwise not be able to be bonded into a new material, or only with great difficulty. It works in three steps: Firstly, the green compact is compacted, during the second step the porosity is minimized significantly and finally the required material strength is achieved.
inter products are found in diverse applications. For example, in the automotive industry, in the form of bearing shells, engine components, brake pads, etc.; dentistry to make ceramic teeth and veneers.
