Crushable Ceramics – or how a Knot Can be Tied in a Ceramic Pipe
Crushable ceramics or just “crushables” for short, are a highly unusual niche application for ceramics. With conventional ceramics, the usual aim is to achieve a high level of mechanical strength. With crushable ceramics however, the aim is to achieve a defined level of mechanical strength that is generally very low in comparison to conventional ceramics. The mechanical strength is defined within certain limits, such that this strength is sufficient for the necessary production steps during manufacturing and processing, but is also sufficiently low for the later compaction. In the following section, commonly used materials, their manufacturing, properties and their typical applications will be described in more detail.
