Special Catalysts for Hydrazine Decomposition
Catalysts for hydrazine decomposition have been produced by Heraeus for several decades. Since taking over the technology and production systems of Solvay, Heraeus offers a special Ir catalyst for space applications.
Engines for space probes and satellites must function with special precision and reliability and meet the highest standards of quality. They represent the essential feature of single-fuel thrusters that develop their thrust by the decomposition of hydrazine or hydrogen peroxide.
