· JVASP-18635· HoBiPt

HoBiPt is a ternary refractory metal alloy composed of holmium, bismuth, and platinum, representing a specialized high-performance metallic system developed for extreme-environment applications. This material combines the elevated melting points and chemical stability associated with platinum-group metals with holmium's rare-earth properties, making it relevant for research into ultra-high-temperature structural applications and specialized aerospace or nuclear contexts where conventional superalloys reach their limits. The alloy is not commonly used in mainstream industrial production; it remains primarily within the research domain for investigating advanced intermetallic phases, catalytic properties, or niche high-temperature engineering scenarios where cost and material availability are secondary to performance.
