Space Propulsion Systems

Over the years, Heraeus has established itself as the independent market leader for iridium-based (Ir) catalyst systems that are utilized in the decomposition of hydrazine. We have long-term experience in the development of iridium-based, ruthenium-based or bi-metallic systems for monopropellant thrusters since the beginning of the 1990’s. Over the past 40 years, our ‘work horse’ the industry leading H-KC12GA catalyst has established itself as the proven industry standard in hydrazine thrusters. The catalyst is economically produced and are therefore readily available, subject to customer specific requirements.

Furthermore, Heraeus has been actively exploring and testing non-toxic, or green propellants, as a possible replacement for hydrazine based propellant offering significant economic benefits. Our patented platinum-based (Pt) catalysts find application in the decomposition of hydrogen peroxide (H₂O₂), especially of High-test peroxide (HTP).

We have significant experience in dealing with the strict demands of the aerospace industry and consistently deliver high-quality precious metal-based solutions to our customers. Customarily, our catalysts are adapted to specific customer operating requirements and can consequently be supplied in different mesh sizes.

As the leading global supplier of space propulsion catalysts, Heraeus has a vital interest in playing an active role in the development and industrialization of components and propulsion systems using non-toxic propellants.
