The fundamentals of brazing, the six steps of successful brazing and brazing techniques.

Mobile emission controls: Johnson Matthey's Three Way Filter (TWF®) technology can reduce particle numbers by 50 ‐ 90% on gasoline direct injection engines.

Through our exclusive partnership with ProSim we can enhance plant performance through diagnostics and optimisation of the entire nitric acid process.

Our cutting-edge technology delivers tailored ceramic products with flexible geometries and feature sizes down to just 400 µm. This process is fully scalable, offering a cost effective solution for producing small complex ceramics.

Additive manufacturing of speciality metal powders is a cost effective method of making complex shapes and iterative designs with reduced lead times.

Each of our bespoke platinum based gauze catalysts for ammonia oxidation is made to meet customers’ specific requirements, with unique production and knitting patterns.

Johnson Matthey’s CATACEL SSR tailored catalyst technology is a proven high performance, direct replacement catalytic solution for producing hydrogen from natural gas through the steam reforming process.

Mobile emission controls: many diesel particulate filter (DPF) systems incorporate an oxidation catalyst, either as a coating on the filter or as a separate element.

Mobile emission controls: a diesel particulate filter (DPF) removes particulate matter from diesel exhaust by physical filtration.

Mobile emission controls: nitrogen oxide can be removed from a lean gas stream by chemical adsorption onto a catalyst, hence the term nitrogen oxide adsorber catalyst (NAC). The process of adsorption releases carbon dioxide.
