Industrial furnaces for the heat treatment of thin-layer ceramics and ceramic foils

Perfect product quality from pilot to mass production furnace

Thin-layer ceramics and ceramic foils are a type of ceramic that possesses a very low thickness in relation to their overall length and width. Typical applications are solid oxide fuel cells and solid-state batteries, amongst others.

Thin-layer ceramics and ceramic foils are inorganic, nonmetal and polycrystalline. 
The green part is usually made by combining ceramic powder with organic binder and other liquid, and giving it its final shape, or applying it to some sort of carrier. They receive their typical properties after a debinding and sintering process at very high temperatures.

ONEJOON mastered the technology to control the firing curve and atmosphere required in the manufacturing of thin-layer ceramics and ceramic foils. Our expert engineers are aware of the unique challenges faced in the manufacturing process and can help you deploy the right tools and equipment to face them. 

One of the biggest challenges in debinding thin-layer ceramics and ceramic foils is proper binder removal, as well as hot-spot and carbon deposit prevention. ONEJOON furnaces achieve this by controlling the homogeneous flow of process gasses through the kiln furniture and over the product. 

Precise temperature control not only in the individual control zones, but in the entire feed, ensures highest product quality and process repeatability.  

ONEJOON validates and optimizes the kiln furniture, firing curves and process gas flow via CFD simulations.
Our CFD simulation models are validated through real world measurements, tests and experiments in our test center or on site, wherever possible. The gathered data is continuously applied assuring and improving the accuracy of our models and simulation results.

Processes

Sintering

There are many different sintering techniques and sintering processes, resulting in different properties of the sintered product. However, an end product with a reproducible and exactly defined microstructure is desired. The furnace technology is adapted by our engineers to your specific requirements and needs.
