Trade fairs in 2022

For WZR, the ceramitec in Munich is the most important trade fair. There we meet almost all our customers and establish important contacts with new customers. This year it was finally time again: after 4 years we could present our topics to an international audience. We had chosen a joint booth with Rösler CeramInno and concr3de, an exhibitor team that fitted very well.

Applications and manufacturing of ceramic membranes

Ceramic membranes are gaining interest as they offer the fuel and chemical industries a way to use renewable resources (Power to X, chemical energy storage, CO2 conversion, Power to Chemicals). They are used in electric motors as fuel cells, electrolysis cells, but also in the production of basic chemicals with high value-added potential. These applications are highly complex systems in which chemical processes (molecular decomposition into ions and recombination of ions into molecules) take place at the ceramic membrane and are catalytically controlled.

Ceramic vs. Plastic – Why are ceramics oftentimes more expensive than plastic

Everyone has already come across supposedly expensive ceramics in everyday life: Be it the Sunday dinnerware, the ceramic knife or the bathroom sink. If you compare these prices with those of everyday plastic objects – garden chairs, mugs or toilet seats – you will quickly get the impression that ceramic objects are always more expensive than those made of plastic. Is this justified and is it true at all? To get to the bottom of this question, we first need to take a closer look at the two groups of materials.

What do you need to know about the fracture toughness of ceramics?

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.

For whom are microstructural investigations interesting?

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.

Material development at WZR

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.
