Compaction of ceramic powders
Compaction of ceramic powders is a specific forming technique for ceramics. It is a process in which ceramic granular materials are made cohesive through mechanical densification, involving (hot pressing) or not (cold forming) temperature exposition.
The process permits an efficient production of parts ranging widely in size and shape to close tolerances with low drying shrinkage. Traditional (for instance: ceramic tiles, porcelain products) and structural (for instance: chip carriers, spark plugs, cutting tools) ceramics are produced.
Cold compaction of ceramic powders ends up with the realization of the so-called green piece, which is later subject to sintering.
== The background: traditional & advanced ceramics ==
Ceramic industry is broadly developed in the world, so that only in Europe the current investment is estimated at € 26 billion. Advanced ceramics are crucial for new technologies, addressed particularly to thermo-mechanical and bio-medical applications, while traditional ceramics have a worldwide market and have been suggested as materials minimizing the impact on the environment (when compared to other finishing materials).
