· JVASP-51290· HfGeB2

HfGeB₂ is a ternary ceramic compound combining hafnium, germanium, and boron, belonging to the family of transition metal borides and germanides. This material exists primarily as a research compound with potential applications in ultra-high-temperature environments and advanced structural ceramics, where its refractory characteristics and thermal stability are of interest. While not yet widely commercialized, hafnium-based ceramics in this composition space are being explored for aerospace and high-energy applications where conventional refractories reach their limits.
