Our Precious Metal Products Division has built on its core knowledge of material science to develop an advanced manufacturing technique that produces novel ceramic substrates

The technique is additive layer manufacturing (ALM, also known as 3D printing) which is used to form ceramics of new geometries. If a shape can be drawn, ALM can fabricate it. This is unachievable using conventional manufacturing techniques, so ALM creates a step change in production that offers freedom in the design of new products.

Increasing efficiency and reducing costs

The ability to change the shape of ceramic substrates helps to control the flow over a catalytic system and reduce overall system pressure drop. This increases the yield and efficiency while reducing the operating costs of a reaction system.

The development of these new substrates draws on skills and know-how from different teams within Johnson Matthey to characterise the product and understand how the process compares with conventional techniques.

One technology, many markets

Our progression in ALM will help us continue to grow our business and move with our customers' changing needs across multiple markets, from automotive to chemical synthesis. We continue to collaborate across our divisions to unlock the technical potential of ALM substrates for Johnson Matthey across a range of applications.
