PtRh10 DPH is an oxide dispersion hardened grade of PtRh10.
It is commonly used for applications in the glass industry, e. g. the manufacture of feeder systems. PtRh10 DPH is characterized by high resistance to corrosion and high strength with excellent ductility in the high temperature range (up to 1700°C).
The hardening which results from the oxide particles, represents the most effective strengthening mechanism of the material. Due to the modified microstructure, DPH is considerably less sensitive to corrosion processes along the grain boundaries than comparable materials. These characteristics allow for extended life and results in the precious metal to be used more economically. An example would be reduced wall thicknesses of PtRh10 DPH compared to PtRh10 or increased lifetime.
