We make crystalline diamond.

The company DiaCCon offers crystalline CVD diamond coatings on metallic or ceramic components, in particular diamond-coated mechanical seals and bearings and diamond electrodes.

In addition to straightforward job coating, our primary focus is on joint process development with the customer in order to produce individual, diamond-coated components that are ideally adapted to withstand extreme loads.

The employees at the company DiaCCon GmbH are able to make use of the experience gained from over twentyfive years of research in collaboration with the Chair of Materials Science and Metals Technology (WTM) in Erlangen, and thus come up with a coherent concept for almost any application. More...

The centrepiece has arrived!

DiaCCon recently celebrated a big day. The vacuum chamber for our new coating facility has been delivered. It was very impressive to finally see the result of months of joint development work sitting on the back of a truck in the early-morning sunlight.

For a customer, we were able to supply a particularly interesting test installation for treating difficult wastewaters with diamond electrodes. Thanks to the compact structure, it includes all the components that are needed for an industrial installation and is largely parameterizable. This means process development and upscaling can be done easily.

„Things are moving now…“

Our new coating plant is slowly taking shape. Now that the planning and design stages are over, the first major structural components are arriving on site, sometimes after a considerable delay in their delivery. The power supply has also recently been established after a joint effort.

“More square meters…”

In response to ever-increasing requests for larger projects with diamond electrodes and shorter delivery times, we’ve long had the idea to develop and build a specialised coating plant just for high-yield diamond electrodes. This plant is now becoming a reality.

This year DiaCCon will be at Aquatech 21 in Amsterdam, the world’s leading trade exhibition for process, drinking and waste water.

This is where we will be presenting our solutions for electrochemical water treatment and synthesis using boron-doped diamond electrodes.

We look forward to seeing you at our stand 02.320C.

"These four fully equipped DiaCCon electrolysers with an anode surface area of several square metres have recently started on their journey to the Far East. There, they will be stripping harmful dyes from waste water. We have taken the opportunity to show this sophisticated technology in all its glory.
