Synthesis Process for Heat-Resistant Pt–Pd–Rh Alloy Powders Using Molten Salt Method

Platinum group metals (PGMs) are vital in catalysis and electronic materials, yet their supply remains unstable due to concentrated primary production and limited substitutability. Conventional powder synthesis methods struggle to produce submicron PGM alloy powders with both controlled morphology and high thermal durability, creating demand for alternative approaches.
