When describing the properties of technical ceramics, we primarily talk about strength, or more precisely, flexural strength. Ceramics generally have a so-called “catastrophic failure behavior”, which means that ceramics break suddenly and without “warning” when subjected to mechanical stress. This behavior can be well illustrated by determining the flexural strength in a bending test, as Anika Braun has described thoroughly on our homepage.

Why combine the advantages of two materials, such as metal and technical ceramics, in one component, and how is it possible?

The coating of ceramic powder particles has recently gained importance and is therefore used more frequently.

Binder jetting is one of the 7 3d printing processes, depicted in the standard DIN EN ISO/ASTM. In addition to vat photo polymerisation (VPP), material extrusion (MEX) and material jetting (MJT), binder jetting is used to produce ceramic parts as well.

The microstructure of a material is one of the most important parameters – if not THE most important – to be used to assess the quality of a newly developed material or component. Therefore, information about the microstructure can be obtained by porosity measurements or strength tests, since these properties are greatly influenced by the microstructure. Directly, the microstructure of e.g. technical ceramics can be studied using a wide range of methods that have been available to industry and the end-user market since the last century to complement conventional optical microscopy.

Whether it´s the Porta Nigra, castles from the medieval times or the ancient wall in the parallel street: the natural look adds a certain charm

Development, use and monitoring of new materials: Our customers’ daily challenges are also ours. To this end, we would like to provide an insight into our thinking and approach today.

The newly developed high temperature resistant coatings are now called CerCoat®-HT. The basis is a ceramic suspension that enables adhesion to metallic substrates with special binders. A temperature-resistant bonding is achieved by a heat treating process between 500°C and 650°C, which ensures the subsequent application temperature up to at least 650°C.

Have you ever had the problem that a metal door just wouldn’t close in the summer, and in the winter cold air came through gaps even more so?

Maybe not, but you’ve certainly had a glass shatter because you poured water inside that was too hot.

Vacuum hot casting is used at WZR to produce first parts of series character quickly and cost-effectively. A major improvement has now been achieved in the preparation of the hot casting feedstock: WZR has now succeeded in both extremely homogeneous and abrasion-free production. The ceramic components produced in this way are characterised by an undyed surface, very low porosity and high bending strength.
